I honestly have no idea lol. The factory plug isn't even plugged into anything. Just zip tied up 🤷♂️ I guess my car still sees its getting proper voltage and says oh well? I've been thru e-check no problem w it.
When I hook up my obd2 scanner up to it tho, it does say over voltage cuz I'm charging at 14.8v and supposed to be at 14.0v flat. But no dash light. After all the customization I've done to it, I'm surprised. I get a light on dash for individual interior lights going out lol.
Nice good for you I just got done installing a gm alt in my old but clean lol 02 MBE320 and I’m also charging at 14.8 but got a dumb red massage on dash I’m okay with the massage as long as this doesn’t make it go in to limp mode I should be fine thanks for answering the question though I’m looking high and low for some info on topic hey sense your cool with auto tech can you ask about my car problem my alternator is basically the same as your just different bracket also it’s just one wire on the harness to the regulator maybe there’s a way to trick the massage Off again thanks!
