Starting problem

SmBlkFord · 12-08-2013, 09:21 PM

All connections are new crimped and soldered , what would be an average drop in voltage when cranking at the starter ? Thanks

Usually .1 volt or less on positive cable and .2 volt or less on negative side would be considered acceptable.None of course would be better. Bad Ignition switch or wiring connections can cause a start relay to click also.

Both cylinder heads are grounded to the frame , I was told to ground them back to the battery ? Would 2 batteries solve the problem ? This car has just recently been re wired , but will check again . thanks

If both heads are grounded to the frame, and the battery negative is grounded to the frame, you should be O.K. Two batteries are not required.

Make sure the starter mounting to the block is clean and free of paint. That is the ground for the starter itself!

Have you tried bypassing the neutral start switch?

All good replies, have you checked voltage at the "S" terminal of the relay? Should have B+ there. As mentioned make sure the starter is grounded properly. BTW what is the battery voltage reading during your issue? Personally I've found voltage drop to be the cause with a slow crank, not normally for a no crank but it's worth checking. I like to have a ground from 1 starter bolt to the frame, just to be sure. Good luck. Joe
