New altenator

[rfischba1]

I installed a new Delco replacement altenator on the passanger side of my m1008, still not showing a charge on alt guage in truck, and #2 light stays lite. Meter reads 14.5 showing a charge.
I noticed a broken wire on the buss bar, could this be my issue with the light staying on and alt guage still bellow green zone. I attached a pic of the small broken wire.

Check the gauge, maybe just a bad gauge. Also what combined voltage do you get when running?
The TM has a great troubleshooting section for this. Voltage should be around 27??? when both alternators are working and batteries are good.

Should be 29V running or close to it.

NAPA carries isolated ground alternators.
