Re: Hard start question

Ok, I did a series of tests:
all cranks are for 5 seconds.
unhooked power to HEI

beginning btty volts 12.67
btty post to post cranking drops about 1 volt

leads of multimeter: + btty to starter main line 000
" " cranking .25 (so 1/4 volt loss?)

leads btty - to starter case .2 loss
" " cranking .25 loss

I also checked "s" terminal:
+ btty to "s" terminal
12.47 volts (my btty is draining from tests, I think)
+ btty to "s" terminal cranking .96 (so I'm losing a volt?).

btty voltage after tests is 12.4

btty cranking now is around 10.7

hooked up power to HEI so it would start:

started immediately, but volts went down to 10.6

I really don't know if these numbers are ok. I'm thinking the btty is not staying as strong as it should during the tests?
