Technical Alternator + starter motor questions

[Pep0]

The plastic cover is on the battery positive

The voltage to the alternator and to the big starter bolt should always be 12V, the starter relay is in the starter I think one of the real mechanice should confirm...

I'm no help as I get through a box of labels when I take electrics apart...

And I'mm of line in Scotland rest of week

hmm should read 12v even when the key is turned to the off position!

Yes, the main power goes to the starter all the time. The solenoid is what switches that power on, hence the second, ignition switched, cable.

But both of the solenoid and the starter motor (the big black cable), both having a constant 12v even when the ignition is at off.

Another weird thing is, when the battery is connected the voltage drops from 12v to less than 2v!

It just seems there is some sort of short circuit going on here!

Thanks

I'm back, sorry no web access in Scotland, been to Moray Firth and back.

If the starter has 12v on both connectors when you connect the big stud to the battery the relay in the starter motor has welded shut.

You need a motor refurb or to rebuild it yourself, but there may be a lot of damage.

Ah cheers pepo, thinks fingers got a second hand starter.

One problem down, right even with the starter unplugged, still none of the electrics works (head lights, hzards etc etc)

What could that be ?

Thanks

main big fuses near the battery under the bonnet?

I can't seem to find that, is that different to the one just behind the ECU? (bare in mind this is a 899 cinq)

Thanks

Got 2! PM me if you want one!

Got 2! PM me if you want one!

Yes yes will do mate . once i get the elextrics working then will pm. Umemployed at the mo, so need to watch what i spend my remaining of my cash .

Does anyone know how to test a starter to see if it is completely ****ed?

Thanks
Ming

 

[fingers99]

Best you can do is connect it to a battery. You can test the motor and solenoid seperately.

Don't think the starter has a problem.

I am sure ycming will be along soon.

Big massive thank to David . I indeed did put the wrong wire onto the starter!

The starter on it now are the one fingers sold me. I'll keep the old one if is not broken

again, the car is now one step closer

Thanks again!

I now have your starter cable handy, just need to go to the Landy to get the other end.

Man this has taken me so long and is close to being ready!!!!

Thanks again David and everyone that has contributed!!!

At last! Good work everyone.

 

[rallycinq]

Still a bit to do to finish the full job, but the engine sounds a wee sweety.

Strange wee thought, didn't see the alternator light on the dash, so maybe the wiring needs a tweek.

[ycming]

As in the wee wire for the alternator light?

Thanks
