2G Alternator & Engine Performance
Hello Everyone, I'm in the process of gathering parts to swap my truck's (signature) 75 amps 2G alternator for a 3G 130 amps. One of the reasons is the dimmed lights when doing a night time stop, the volts gauge going to the low side when everything's on plus the fire risk as well.
My question is: Having a 2G 75 amps alternator could cause the engine when pressing the gas to feel & sound like stalling this usually happens at a stop sign with the AC on
At this point I don't have CEL..
Thanks!

When you do the 3G swap, you have to upgrade the power wire to a 4g wire. I also advise to put another ground in and match it with your power wire. IMO if you have a 4g power wire, you need a 4g ground wire. Just to be on the safe side. But I have heard of people not doing the ground and getting away with it. (I did a 3g conv. on my Mustang and did the ground) And about the idle issue, I have no clue. But you CAN have codes even with the CEL off.

AND a 2Ga. ground from battery to frame, to block.
The entire charging system is only as strong as its weakest link.
If you have a winch, electric fans, huge Amp, whatever...
Protect it -and your harness- by using the proper cables, Megafuse and connectors.
