Default MS2E Alternator Help

Hey guys,

When I first got my Rev box, it would have random issues of undercharging and overcharging.

It went away for awhile, but it's been slowly coming back. Could you guys take a look at these settings, and see if there's an issue here?

Normally I get 13.4-13.5 idle, cruise with no electronics on.

If I cruise with lights, heater/AC I get about 13.2-13.3

The problem is when I go WOT. Sometimes it'll randomly overcharge or undercharge.

There's been times when it undercharges and I don't know, until it's about to completely die. Since then I've installed a voltage gauge to monitor it.

Also, if I cycle the key it goes back to normal.

For example;

WOT 1st, shift 2nd then all the warning lights come on for a second (CEL, ABS, BRAKE) then it'll undercharge. Cycle key, and all is well.

WOT 1st, shift 2nd, all warning lights, but then everything just stays illuminated, and super bright. At that point, we know it's OVERcharging. I'll look at my voltage gauge and it'll be at 19 or so volts.

Can anyone see an issue with these settings??
