Starting problem

[SmBlkFord]

How to do use go about checking amps drawn at the starter ? My relay clicks away sometimes , running 1 12volt and alternator , charging between rounds , last thing I try before using another battery .

Current draw would only be an issue if the starter was actually engaging and trying to turn the engine over .
The starter relay only clicking can be the result of several issues , the most common one I see is voltage drop across battery or starter cable connections , especially ground cables .
Start with fully charging your battery and having it load tested to confirm it is up to par .
Check for voltage drop at various points of both positive and negative sides , starting at the battery posts any working toward the starter .
You should test both at rest and while cranking .
Cable ends that have not been properly crimped and soldered are the worst culprits . Clamped or compression type lugs should be replaced with crimp and solder connections .

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.
