Hook Starter Backwards and bendix kicks out

[oldmanactingyoung]

Hi all i posted this in premium section but thought i might here also. Not sure if i should have there or here...But got a strong starter ( spins very well sounds good when turning ) but hooking up Ground on front and red on Back ( jumper cables off car Not running ) starter turn very fast but bendix does not kick out...reverse Cables ( pos in front Neg at Rear ) and bendix Kicks out immediatly and starter still turns and sounds strong...got me confused unless solonoid reverses polarity when power does thru it ?...bad starter or something else...

I bought a seadoo 95 GTX and the guy Gave me this one ( 97 GTI Looks Great No scratches or anything very clean in hull ) and starter was already loose from wires but still mounted to engine....I did find out that he jumped it with truck last time he was at lake got 100 yards from dock and it died and would not start no power to anything ( he blew MPEM when jumping it ) and i have MPEM now at all things custom getting repaired but i am checking everything out to be sure all working ok before i get Mpem back. I tried starter by crossing solonoid and it spun strong but bendix did not kick out so i pulled it. any help be appreciated..

Are you positive that you do not have it wired bacwards?:cheers:

Wired Backwards ?

Hi Robin Good to hear from ya again lol

Have the Starter wired Backwards ?. I had the starter off the Ski and Hooked Ground onto the Bolt where the Ground Came from when on ski ( when i took ground off i Threaded Bolt back in hole so i do not lose it ) which is on the Front of the Starter close to Bendix...the positive cable i hooked onto the stud which comes out about 3/4 the way back on the starter it also has 2 insulated washers on it and 2 Regular washers on it along with the nut of course it is on the side of the starter...Is this the Correct Connections ?...gonna be embarrassed if not lol been working on auto's since i was 10 but jetski's are new to me ( i just fully Restored My 69 Vette from Ground up naked frame to completion ) I have some Mechanic Skills but again these jetski's are new to me so i could have it wrong..

when i got it also to let you guys know ( i feel this could be an issue ) the guy told me he had done no work on it at all that it died on him after he jumped it and got 100 yards from the dock he said he parked it and never worked on it ( this was the 97 GTI he gave me ) now i know he changed solonoid as there was another solonoid in the box up front and also the starter wires were off the starter totally ( hooked all that back up ) So someone did some work to it. this was when i found the blown fuse next to solonoid ( 15 amp ) when I replaced it 5 amp fuse Blew ( we know now that is MPEM Bad and its at Mikes now getting repaired ) Probably caused by him jumping it with truck. what im thinking is he Traced the issue and figured out the MPEM was blown and knew it was costly ( 800 Bucks at dealer ) and was afraid i would not have bought other ski if he told me the truth ( im assuming here ) seemed like a nice guy but u never know . I dont fault him i would have bought other one anyways and i got a free ski that needs work.

My question i guess is could he have hooked the Solonoid up Backwards and would that cause the starter to reverse Polarity ?..or would it just be a bad starter. Or am i totally missing it here and when hooked up correctly ( the solonoid ) actually reverses polarity to starter and thats assuming he has it backwards on solonoid ( really dont see how it could but again jetski's are new to me ) . I am truly sorry this is so long but I feel without you knowing some history of the ski ( as much as i can figure out anyways ) then this would make it more diffucult to figure out. and again thank you to all you who make this site so helpful :hurray: again sorry if this seems confusing or if i am not explaining correcly let me know please ill to to get it right

 

[robin savell lloyd]

I am puzelled I do not know what is going on I do not thank that you could install solinoid backwards. I know that they use rotex on air planes and I do not know which way the engine spinns on a air plane and I would dout that this would be the problem. I wander if it is possable to wire the starter to where it spins backwards. that is the only thing I can come up with sorry. I hope it is a easy fix. good luck Robin :cheers:

 

[oldmanactingyoung]

Thanks again Robin

I did not think I could wire starter Backwards or i would have a Hot from Battery where Ground would be that would short whole system out. As Far as the solonoid i think it can be wired backwards not really sure tho as again i think you would be back to a direct short...so all that left me was a starter that is running backwards..i was fairly sure that there was something with the starter but just want to be sure before i buy another...hate to buy one when i got a strong spinning starter then find out that seadoo's are built where the starter might be able to be changed somehow and work correctly...i do thank you for the info and taking the time to answer...:cheers:...maybe someone on here can give me the answer to this one lol..could have been something this guy done that i cant figure out and will be a simple solution...Fingers are crossed lol

ok, you have a screwy starter. it is possible you may have one that had an armature that was wound to spin the opposite way. these are neg ground systems. you have that right. sol does not reverse polarity. try starter from the other doo. they interchange. you have obviously had enough practice removing them by now.

Has anyone put a volt meter on the battery??? I bought a motorcycle one time dirt cheap because it wouldnt start. The guy had charged the battery backwards. (I didn't believe it either) but it spun backwards and blew fuses.:cheers:

 

[oldmanactingyoung]

Hi Boone i did put meter on battery and it tested fully charged. red to pos ect and had correct charge and also used jumper cables off of car on starter ( off ski ) when reversed bendix kicked out immediatly. when hooked correctly starter just spins very strongly but bendix does not kick out.

My point or where i am curious this guy said he run the ski and used it before it died. what could make starter start running in reverse or did it just go bad ? or am i doing something wrong here. looked at manual but it does not cover starter running in reverse.

 

[mboone71292]

Has someone had the starter apart? Maybe the brushes are not in right. do the alignment marks on the starter case and cap line up?

 

[kustomkarl]

:agree: if it was disassembled it could have been assembled wrong ...go check.

This is something very intresting I could see that it may be possible. I am going to search it further to comfirm that it is possible. :cheers:

Hi Robin.

I had Read in a Previous Post where someone had a reversed battery on a ski so i tried it on a Car battery Just to be sure. Had same Results....Thanks for taking the time guys im stumped on this one...

Boone and Karl You could be right There could have been work done on starter Maybe possible rebuild ( he could have thought that was the problem so had it done ) is there anywhere i can get Diagram of starter so i can see correct way for it to be assembled...guess i could just buy new starter but hate to spend anything on new one when this could end up being a simple fix. and i actually like the challenge hehe..ill look in manual also see if by chance there is a Diagram in there...thanks again guys :cheers:

I checked but could not find any thing about the battery being charged backwards and being able to hold a backwards charge. I thought it may be possable that if you had a new battery and it was completely dead because you left something on that you might be able to get a reverse chage by hooking up charger backwards. I have never done it so I did not no if it was possable. The only thing I can find is that someone may have wired the inside of starter incorrectly. Good luck :cheers:

 

[oldmanactingyoung]

Well the manual has Amazed me again it has Internal assembly for the starter in it...gonna check it out..thanks for advice guys

 

[oldmanactingyoung]

Ok Boone I think you got it...I looked at starter and on the Rear Cap There are 2 marks on it. then on the Casing there are 2 marks on it but they are faced towards the front of the starter ( the opposite end from rear cap and are not in line with the 2 marks on rear end cap ) they are about an 1.5 inches off the 2 marks on cap...would that cause starter to run backwards ?

 

[mboone71292]

Bingo. I think you found your problem

 

[oldmanactingyoung]

Here is picture of starter can you tell me the correct way to assemble this please ? the arrows tho hard to see show where the marks are...thanks

 

[oldmanactingyoung]

WooHoo got it

Thanks guys your advice was perfect...got the case off cleaned inside while i was there. assembled starter to match lines to notches and it kicked out perfect...way to go guys...excellent help and advice from all...site paid for itself again....glad i got that premuim membership saved about 600 bucks already on parts that i would have bought...:cheers:

it is possible to put the field housing on at 4 different clock positions. 2 will work, and 2 will spin backwards. looking at your starter, i don't see the battery post. i think it should be in sight in that picture. the 2 bolts that hold starter to engine are at roughly 11 and 5 o;clock. the battery post should be pointed up and slightly out at about 10 o;clock. if it is pointed down at about 7 o;clock, the starter will spin backwards. so, if the brush holder end is positioned correctly and starter spins backwards, pull the 2 thru bolts and rotate the field housind either way 90 degrees. then reinstall and try spinning it with battery. there should be a notch the housing and brush holder want to drop into to align correctly. they aren't very big, and can be squished until they are no longer effective.

Got It Running

Hi Guys

Just wanted to thank you guys for all your help. Got starter turning correct way but when i put it on Ski it spun about twice then started jumping then would not turn over motor. So i am sure it will be best to get a new one.

On a good note i got my MPEM back from ALL THINGS CUSTOM and they did a Great job ( i stole wifes starter off her ski :rofl: ) but installed MPEM and the ski runs GREAT ran it 5 minutes with hose and from sitting 2 years it smoked a bit but that cleared up went out 1 hour later it fired on 1st turn and ran great for 5 minutes...cant wait for my 1st ride ever on a jetski this weekend :hurray:.... thanks for all the help guys you made it all worthwhile...Kudos to you all...thanks again. and i hope to return the favors by someday down the line by helping others out on here :cheers:
