Update finally figured it out it was the fan diod. Thanks C-note for your input. The fan diode RAL 254 "diode symbol" 704 on my 2008 AC 700 efi 4x4 h1 se my next question is where can I buy a new one and ifi could get a model or part number. The only info I seem to be able to find is up to a 205 AC 650.
That diode only protects the fan from receiving too much voltage, and/or receiving voltage if polarity is reversed. If that’s bad, the fan will not receive its “ground” when needed, not any polarity changes due to accidental reversing of power leads anywhere.
Chances are, that something else caused your overcharging, and took out that diode in the process. Have you ever jump started unit, maybe using “Boost” setting on a charger? That could possibly cause this.
Or possible reversal of polarity (by accident of course, as mentioned 2 paragraphs above), as that will smoke diodes as well.
Below is wiring schematic in full size, that diode (circles and tagged in red) is nowhere near the portion(s) of the ground circuit required to bleed off excess voltage when required. As long as that black harness lead is grounded good, that’s all that’s required for voltage bleeding during operation of unit.... 🤔
Who, me?! Don't listen to me.... (I don't know anything, evidently...)
If it's cnote approved it will work good
That is freeking sick man........
