jmurray01 Posted September 21, 2016 Share Posted September 21, 2016 I'm in the process of determining what the problem is with the GTX in terms of its poor/no starting due to slow cranking, even with a fully charged battery. I suspect (or hope!) it is just one of the negative grounds somewhere that is corroded and needs cleaned, but I can only find one and the trying to find the other one has initially proved unsuccessful. A thought came to me today though, that in order to test if the grounding is the problem or not, I could just run a jump lead from the negative terminal to a ground point (with the terminal connected of course), and that would then ground the battery if the original ground is ineffective. Am I right in thinking that? If so, that would quickly tell me if it is a problem with groundings or not, and if it makes no difference then I'll know it is something more serious such as the starter motor or a seized pulley etc...

A good, heavy, copper jump lead would help. Possibly to one of the bellhousing bolts, or some substantial & clean bit of casting there. Take great care not to short it to the +ve at any time though! I had slow cranking & sometimes fail to crank, it was the solenoid on the starter motor. I could hear it click, but it made bad or no connection to the motor. I did a temporary fix twice by removing the solenoid, and giving it a good clean: Got it going for a while, and proved the point. Eventually I managed to source a replacement solenoid for about £22, but it took a lot of hunting. Quote Link to comment Share on other sites More sharing options...

It's a toss up between that, the alternator or the P/S pump being seized. I looked at the starter today and it actually looks fairly new, like it has been replaced in the last few years, perhaps as an attempt to fix the issue. 1 Quote Link to comment Share on other sites More sharing options...
