New alternator question Options

[Stu37363]

I installed a new alternator 170 amp. it seems to be working great. it drove to the gas station, but then for the first time in years my car wouldnt start and i had to roll start it today. ive got an optima yellow top battery.

I have upgraded the battery ground, but have not upgraded the alt to battery wire or the engine to chassis wire.

I was testing out my alt and was cranking out music, my speakers pulled about 60 amps and the speakers started to get fuzzy and quiet, so i turned the volumn down and revved the engine out of instinct, and it went away before i could figure out what was going on.

I know this is probably a stupid question, but is it possible i blew some charging fuse or something?

voltage shows 14.5 when running and was showing 11.5 when it wouldnt start.

Does the wire from the alt go straight to the battery, or does it split or get fused at any point?

Happy to give any more info, i just dont know what else you may need to know.

Thanks

ok, so had my battery tested and its good.

I put the fully charged battery in my car and tested it for draw.

im not really sure what the reading on the meter means, but i put it on the 10a setting and it showed .10.

i found that my main power run to the amps was pulling .06 and my dome fuse was pulling .02

im not sure what this is a measurement of, but it killed my battery in about an hour.

i tested the remote wire with a test light and it did not light up.

im going to work on this again tomorrow, any thoughts between now and then are welcome.

Thanks

Edit:

Did more work today, got the draw down to .02, which i believe is 20 milliamps, which should be fine.

still didnt help, so im just going to replace the started and hope a bad starter is draining my battery.
