Gen V Swap Alternator
Hi everyone. Just finished a L83 Gen V swap in my 1988 Suburban (attached) and I love the way it turned out. However, I'm having some alternator issues and was curious how some of you fixed it in your swaps.
My alternator performance is hit or miss. Sometimes it will charge at 13.6 volts but other times it won't charge at all. I assume this is because I don't have a BCM and the alternator is just in a limp mode. I don't have a big stereo or off road lights but I do run the front and rear AC, plus dual electric cooling fans, and a fuel pump so I'm concerned that the alternator won't keep pace. Or I won't notice one of the times when its not charging and will drain the battery.
I have heard that adding the 470 ohm resistor to the brown (L) wire in the alternator wiring should fix this (similar to LS swaps) but I have also read that it doesn't work on the Gen V stuff.
Do any of you Gen V swap guys have a solution here?
Thanks,
Chad
