Hey all, now that I am driving my 164Q a bit more often, I am getting accustomed to its niggles etc. (I had to wire a relay direct from the battery to get the radio to switch on without the engine running)... Fixed most little things so far but when I was in heavy traffic yesterday for an hour or so and parked - the car wouldn't crank afterwards... I left the bonnet open for 15mins or so in case it was heat related. Eventually it decided to crank and started and ran fine again.

Which relays are directly connected to the starter motor circuit? When I tried to start it I had accessory power (all lights came on dashboard) but there was no noise from the starter motor - no clicking or anything... Makes me feel that power wasn't getting to it (I could be wrong!).

My foglights came to life after replacing the associated relay - maybe this might be a relay issue too?

thanks :)

I have no factory alarm system on mine so it may not be linked to that, it happened to me once before too but when the car was stone cold...

In that instance replacing the battery with another one I have allowed it to start. Symptoms are almost like the ignition switch is failing or one of the relays the power goes through to get to the starter motor (but I don't know which relays are the ones!).

all good points, thanks Del - my battery is a new gel battery that sits on 14 volts with headlights on so I think that is ok - it could very well be the grounding or connections on the starter motor (forgot to look at those :) ).
thank you :)

Thanks for the info Del, with the radio - my wiring for that was butchered so I had to start from scratch - only three wires needed anyway :)

I may have found an easy solution too - not sure if it will work since I haven't tried but on another 164 forum I'm a member of they suggested using the trigger wire that goes to the starter motor solenoid and putting it into a relay and using 12V straight from the battery to 'be' the power for the solenoid when the key is turned.

That's what I did for my radio, it might work in this case too :)

Just an update...
Ran a wire direct from the positive on the battery to my own relay in the engine bay mounted next to the 50amp original and used the trigger wire to let the direct 12V current go straight to the solenoid while cranking - works a treat and cranks A LOT faster now, starts first time easily :)

Thanks everyone for the help :)
