Starter not working full stop!

G40 AD · April 17, 2010, 08:32:21 AM

right quick update...
happy to see that i got a 12v reading with the engine off and 14v with the engine on!

I can only guess though that this means it isto do with earthing as sufficient power should be going through the starter motor if the alternator can still produce 14v??? am i correct in thinking this?
going to fit new wiring now just for piece of mind!

ok... just had the relays off and they looked a bit grubby/greeny so cleaned them and the sockets... is there a way of testing them?
just tested;
negative to starter: read 12v(engine off)
negative to alternator: read 12v(engine off)
my assumption from this is that the wiring is all ok, is this a fair assumption?
potentially it could be shorting at some point and still read 12v, correct?
going to clean up the bat terminal but cant see that i would get the 12&14v readings if a poor connection was causing trouble... grrrrrrrrrrrr..........help!

scirocco glx alternator is exactly the same as g40. £37 brand new of eBay - allllllright:-)
if it was doing it when hot- check the wire going from the alternator to the starter. it runs along the sump and the plastic goes manky near the clips and you may find the wire has frayed near them potentially causing a short. I replaced this cable on mine when I first bought the car as it had a hot start problem and it turned out to be this very cable doin what I just described.

This true, cos if it is i'm buyin'.

getting 12v across all the earth straps at the chasis end.....

anyone got any clues?

G40 AD · April 17, 2010, 09:48:10 PM

is there any possibility that the relays could be at fault...
Saf said that he had the same trouble when his bat was kaput...gonna try a new bat tomo...

there is 2 plugs under the right hand side (lokin at the bay) of the throttle top hat one is for the starter see if its got a good connection

Puncharado · April 19, 2010, 11:03:01 PM

Could be the ignition switch.

G40 AD · April 20, 2010, 08:52:42 AM

just to confirm is this the plug at the back right of the TB... just going from memory
or is it the middle plug of the three in the holder where lambada plug sits?!?!

by the ignition switch do you mean by the by the key barrel?
the cd player (run from the ignition) does keep cutting out... loose connection... could this be linked?

thanks v.much for your help guys!

the ignition switch is on the steering column, behind where you put the key in.

The white plug actually on the TB is for the throttle open/closed switches so not that one. It's one of the black ones, thick red/black cable and thinner blue cable.

no joy with the plug... think it cud be the relays... tried another bat didnt work...
how should i test the ignition? best to just remove the steering wheel cowling and check for any visible faults or perhaps with the car running wiggle the wires and see if it cuts out?!
cheers,
