Ah well received a new start relay today plugged it in and got exactly the same symptoms, after a lot of voltage measuring etc. gonna check out the connections further upstream, looks like a voltage drop across the start relay supply to the starter solenoid.
Run a cable straight from battery pos to starter connection see if it spins, that eliminates starter at least? If it does then move cable to output side on starter relay that checks cable to starter, go to other side of starter, possibly need to initiate relay from switch, work back from there until it doesn't spin!!
You have to ‘think positive ‘! The problem has been narrowed down...... Shorting to earth, dry connection or the starter motor solenoid? If you eliminate the latter, as suggested above, you can then concentrate on the wiring and what may be giving way under load.
Finally got her going, eventually come to the conclusion the starter relay was dropping out due to a drop in volts to the relay, the cause ? a couple of things 1. there are two wires connected to the Battery +ve one heavy duty to the starter and a smaller one to the fuse box supplying the rest of the systems, eventually found a spade connector on the small wire about 4 inches from the battery hidden under the seat I bypassed it with a wire direct from the Battery the Tbird started yippee, cleaned up the connector plugged it back in, no start!!!. the same setup on the -ve side of the battery cleaned that up as well the starter solenoid would now click in and out a few times which was an improvement, I removed stripped and cleaned the ignition switch. 2. I had removed the bike battery as suspect, was using a 40 Ah car battery and jump leads (3 different sets) as I somehow didn't think the leads were supplying enough power. I waited a few days for a new bike battery to arrive It was subsequently fully charged and fitted. now all is well the Tbird starts with no problems, she is ready to test ride A big thanks to everybody that contributed
Pleased for you. Persistence in narrowing down the possibilities pays off. “Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. ” No S*** Sherlock (Holmes)
Always feels good when you get to the root of the problem and the bugger decides to start co-operating again Result
