Bulkhead Connector Bypass Step by Step
Moderator: Moderators
Just tried it and no different. But! (Big but!) I noticed the stud the cable attaches to on the alternator was "wobbly" I've redone that and it's now reading 12.6v on tickover and late 13v while rev'ing. So I'm hoping that was my issue!

Changed all alternator to starter relay to battery and starter cables for new ones today. Car is starting and running fine. I'm getting 13.5-13.8v at revs, but only 12.5v at idle. Is that ok, or do I still have a charging issue?

All that it's showing you is battery voltage. Under any load mine is always 14v plus (regulated at 14.8).
It must be the charging circuit. Have you run cable direct from alt to battery?

I've run a cable from alternator to the big stud on starter relay, then just replaced the cables from there to battery and starter with new. The alternator looks to be a recent replacement (as in fitted before we bought it but had to be summer 2014) REMY 20160 50Amp unit.Dave81 wrote:Still too low Chris.XP29 wrote:Changed all alternator to starter relay to battery and starter cables for new ones today.

That's not regulating properly, you'll boil the battery on a run. There seems to be a quality issue with replacement Mopar alternators and regulators, for the last few years, the failure rate among members has been very high. If you are not totally worried about 100% accuracy, fit a modern internally regulated Denso alternator and kiss you charging issues goodbye for good.
There are 3 mods I would always advise anyone to do on an old Mopar for reliability, mini starter, Electronic ignition and a Denso alternator.

Oh, Bugger! I'm not sure how good the regulator is in my car, if its original or repo. I have ordered a replacement stock looking unit that has solid state intervals so is supposed to be reliable.

If I do go the Denso route, what's a good 50A unit? Also what wiring mod would I need to do?

Yes alot of people that don't worry about origonality go with the Denso.Blue wrote:That's not regulating properly, you'll boil the battery on a run.

I have a 100 amp unit made by tuff stuff and have not had any problems pricey yes(200 BUCKS), but very reliable

Easily man enough unless you have electric engine fan, fuel pump, stupid big stereo etc. Easy to wire, big cable to the battery, small cable to bypass the regulator, you can fit a charge light if you want still works if you don't. Will fit the stock brackets with minimal work usually.

As I already have the solid state regulator on its way my thought is to try that first. If I have further issue and need to replace the alternator I will go the internal regulator route. That said it seemed fine today, only drove for 1/2 hour to 40 mins though. Now battery with ignition off is testing at 13.5v
