Electrical Help Please

Justn my $.02 but now its $.05 ajusted for inflation... :poke:

1. Check the date code on teh battery it will be a colored dot sticker with something like K-8 (2018)
in this example the battery is 6 years old may want to get a new one most batteries are 60 month and my personal rule is 5 years .

2. You stated high comporession what is the cca 1000 volts? I like 1000 cca for high comp applications.

3. Check for parisitic draw killing the battery. turn car off take key out of ignition hook an ammeter up after you disconnect the battery negative, hook probes or test light between cable and neg terminal,
check amps OR use a test light a nice bright light mens something is drawing off the battery when the key is off..50-80 miliamps on new cars is normal for all the modules aND LESS THAN 50 MILLIAMPS IS NORMAL ON OLD CARS FOR PARISITIC DRAW. Caps lock not yelling. Trunk and glovebox lamps used to stay on they were the culprit usually but in a race car who knows what it could be...

4. If you can get it where it cranks do a load test hook up a volt meter while someone starts the car see if the volts drop to less than 9.6 cranking if it drops to less than 9.6 battery fails load test.

5. is the starter getting cooked by header heat...? if so the car should start after sitting a while...

and not necessarily in that order...good luck :thumbsup:
