Hi as the title says I'm completely new to seadoos .im more of a mechanic than someone that plays with these thing Sadly, but right now I'm working on a 96 gsx that's got electrical problems . The owner winterized it at a dealer and stored it for the winter , pulled it out this summer and it's doing the following: starter keeps cranking as soon as you connect battery power and will fire up only if I hold down one of the vts buttons . Vts works though.
Traced it to the point where if I unplug the two wire plug on the solenoid it will stop cranking . Also checked the start button which is good could it be the mpem? Or even just the diode I've read quite a bit about on here ? Could the mpem also cause it to not run without holding the vts button ? Can someone please guide me as to where I should post this please...
I'm way better at mechanics than wiring I need all the input I can get .

Thanks in advance, lots of good info on here, love it :-)
 
Hi, and welcome to the Seadoo forum.

I would say it's either the solenoid or the starter button switch or in the start circuit. Unplug the connector at the base of the solenoid, if it still cranks it's the solenoid, if not it's in the start circuit.

I unplugged the wires at the base of the solenoid which was mentioned in my first post and when I do that it stops cranking . Start button also checks out good , anything I'm missing? Does the start circuit go through the mpem ?

First,, I will move this post to the 2-stroke forum as you are past the MEET AND GREET aspect (you posted in the Meet and Greet if you didn't realize that).

Humor me,, because something is not right...

How did you test the START/STOP switch? Ohms or volts? And please describe how you did it.

Bottom line, if you unplug the wires from the Solenoid and it stops cranking, the trigger wire is getting power through the START switch or,,, the wire is shorted to something else that is providing a positive (Hot) feed.
 
Thanks for moving the thread for me, I unplugged the start switch and put the battery on and it keeps cranking so that would rule out the start button right? And please bear with me, I think I did mention I'm better with mechanics than electrical

No issues,, we will take is slow enough to get good answers,,,

When you say I unplugged the start switch and put the battery on and it, what did you put a battery on? The solenoid? or the switch somehow?

Do you own a Digital Volt Ohm Meter (DVOM)?
 
Sorry I didn't explain well enough. After I unplugged the starter button I connected the battery to the cables where the battery normally goes (not the solenoid or the switch) and it keeps cranking and yes I do have a digital multimeter but only a cheap one with no beepers or anything

I'm still confused,,, I KNOW I/we can help you, I just need to FULLY understand where we are... LOL

Ok, so you unplugged the SMALL wires from the solenoid, is that correct?

And then you connected wires to that plug? if not, to where? Did you use jumper wires?

Here is a solenoid for example.

I unplugged the base plug on the solenoid and also the start button and hooked up the battery the the seadoo's battery cables . I didn't jump anything to anywhere just the battery in its stock location

Listen,, I do not want to anger you, and I really do know my stuff here, but I can't follow you.

Looking at the solenoid above, you have two large terminals and one plug. The plug is the START/STOP button.. You are saying you unplugged the BASE PLUG (what do you mean), and the START BUTTON, (Which I assume you mean the smaller plug on the solenoid as pictured above)?
 
He unplugged the connector that enables the solenoid. I have a feeling the MPEM is smoked. If you disconnect the start switch its 2 wires, just use a meter on ohms when not pressed it should be open then when you press it it will close, making contact, you should get a reading of 0.001 out next to no resistance. Now if you disconnect that plug from the solenoid and it did I'm pet sure the only thing else in the circuit it's the MPEM.

That part I get, but I am confused on what wires he put on and it cranks,,, Are we talking about the BATTERY wires to where they belong? If so, then the solenoid is stuck.. But I am lost on that part,,,
 
The way I read it was this. He hook up the battery and it cranks. While the engine is cranking he unplugged the 2 wire connector from the solenoid and it stops cranking. So if the start/stop switch is good the next in line is the MPEM, I think

That is exactly what I did , only I didn't test the start button yet with a multimeter, just unplugged it as close to the button as I could and it's still doing that . So it would make sense if it's the mpem , tanks for clarifying racerxxx
 
I was TOTALLY confused when you said something about hooking wires back up...

At any rate,,, you do need to test the switch at this point.
Unplug it like you have been doing. Put the meter on Ohms, put a lead on each wire. It should read OPEN. If it reads zero or near zero without pressing the button, it is stuck closed. Assuming it is OPEN (good), now press the button, if it goes to zero or near zero, the button is good.

Minnetonka4me can test the MPEM. I think he charges a few bucks, but if you buy a used one from him he waves the diagnostic, I think. He will also stand behind his MPEM that it works 100%'

How much does he charge for a used mpem? And where is he located? I'm in Alberta Canada so it most likely has to be shipped
 
He's in Minnesota, he ships world wide. [MENTION=41828]Minnetonka4me[/MENTION] will let you know how much. You can either wait for him to reply to this thread or click his name in blue and submit a private message to him.
 
Got all my parts in and everything is working like new , thanks to everyone who helped out and a speacial thanks to Minnetonka4me for supplying me with parts
