ok dropping a new motor. its freshly rebuilt.. its a b18b in a 90integra, using the b18a harness, dizzy and everything .. the only thing from the b18b is the motor and the intake manifold. i have primed the motor but the problem is that i am losing ground on the motor when i crank it ..
originally i had a fuse inline of the battery relocated in the trunk and it kept popping so i took it out .. the started wont work unless i ground the starter to the chassis with a 10 gauge wire

i put a multi meter on it ... i have the positive lead on a constand 12 volt source and the negative lead on the block .. when normal i have 12 volts but when i crank the car it drops down to about 5-7 volts.

any clue ? please?? anything ??

 

I'm a 12volt installer and 90% of voltage drops are from loose connections or dead cells in the battery.

battery testing is free at most part stores

double check on your wiring.... even pros miss details every now an then.


good luck
