Hey people, I’ve just replaced my starter motor but the beast is giving me no turn over or noise except for the usual beeps when I plug in the dess. VTS seems to be working and oil lights on but no turning of the starter My moneys on the battery ! Before I replaced the starter it would make a click sound when I pressed the start button but now it doesn’t even do that. Any advice would be much appreciated
 
Load test the battery…if you jump the starter directly does perform properly?,,,could be failing selenoid.

I replaced the solenoid that was my first line of thought but clicking still occurred, I’ve. It tested the starter from the battery directly, I stuck the battery on charge and it’s in pretty poor health. The battery I’m using is an ultramax YB16L-B but I’ve looked online and it says I should be using a YB16CL-B, will that make a difference to wheather or not the starter will turn ?

When you said the battery was in poor health,,,did you do a proper load test to determine that?
 
Either buy a load tester…or just it take to an auto parts store and they’ll do it for free.

thank you, the new battery has arrived, charged and installed. Still nothing when I press start. If I bridge the solenoid, the starter begins to engage but no real turn of the engine. Is it fair to say start with the fuses ?
 
Since bypassing the selenoid does not help…either your pump is siezing…or your motor is seizing…
 
So an update I’ve got the starter working and the engine turns over with the plugs out but locks with the plugs in, is that to do with no combustion ?

Without spark plugs


With spark plugs

 
It’s caused by either a weak battery, starter or bad cables.

It’s typically the battery. The cranking system can’t overcome the additional load of the compression.
 
When you crank it over with the plugs out does anything come flying out of the spark plug holes? Like oil? Being as it’s a new battery I don’t think it’s your problem.
 
I was thinking that maybe the inner crank seals that separate the rotorary valve from the rest of the crankcase were leaking.hydrolocking the engine with oil, but if the lines are off and there’s no oil in there then it’s not that. I don’t have much experience, I had read that quite a few times and seen it happen once when I was looking at a 2003 GTI. Wouldn’t turn over with plugs in, fellow took the plugs out and oil was flying everywhere. Did you try and turn the engine over by hand?
 
You can, in the PTO side of the engine (the side to the rear) there should be a plastic cove that’s about 4 inches high, wide and long held on by 3 wing nuts. Under that you can grab the pto and turn it by hand unless something is seized

I’ll give this a try next time I’m down the yard, thank you

So it moves freely when there’s no plugs but still fails to crank when plugs are in I have a new 22ah battery and sounded like it made a turn or 2 then nothing ? I feel like I’m being stupid and there’s a simple answer but I just can’t seem to find it.

I’ve also been reading about starter motors, originally I had an 8 tooth bendix, now using a 9 tooth.

I still have my 8 tooth, is it worth me swapping the bendix over ? Could this be a cause as to why it’s not cranking ?

Si I’m pretty stumped,?i just watched the videos you posted if it turning over with no plugs and not turning over with the plugs in. That really does sound like a bad battery, it you have a brand new one. As I mentioned, I don’t have much experience so hopefully mikidymac or poops will have advice but I would double check the voltage of the battery when under load, I’m not sure What the volts should be when cranking but it seems to me that somewhere you just don’t have the juice to crank it over when plugs are in. To me it sounded healthy when you were cranking with plugs out. I’m only guessing, not really sure, i would have to do research myself but maybe it’s the voltage regulator/rectifier? I’m off today so I will do a little research and see if I find anything. I don’t know about the bendix either, does it still crank over nicely with plugs out? If it does then I would say you are fine there. Also wanted to ask what you meant by “ the lines are off” do you have the oil lines off?
 
I’ve read through 3 or 4 different posts with the same issue and battery keeps coming up. Put a volt meter on the battery when cranking I’ve read a few different values but volts shouldn’t go beneath 11.8 . The hydrolocking was an issue in 1 post, so once your sure the battery is good under load, pull the plugs, crank it for 15 seconds, put plugs in and try again right away. Check the grounds, ground at the starter, battery cables. Make sure they are clean, and put on a little dielectric grease.You can also try jumping from a car battery with short cables but never have the car running and never use a booster pack. Can damage the MPEM.

Yeah still cranks nicely without the plugs in, I’ll dig out the multimeter and check it under load, what I mean by no lines is the fuel lines and oil lines although I’ve replaced half of them now.

I can’t imagine it’s hydro locking but I’m willing to try anything at this point haha when I bought it someone had blown the mpem which I’ve since replace and will not be blowing myself haha
 
You could have a bad starter. What color is it? Even a weak battery will spin the ski over efficiently with the spark plugs installed. I have a battery that load tests at 48% with a full charge and I use it to quite often.

When you tried to jump the starter where was your ground connected? Ground should be connected to the starter ground connection on the starter,. The positive cable to the positive connection on the starter. If the engine doesn't spin pull the starter and look at the brushes. If the starter is black throw it away and buy a good starter.

First pull the PTO cover, you should be able to turn the engine over by hand with the spark plugs removed.

You can also install ONE spark plug and see what happens. Good Luck.
