    Electrical Build Alternator Question

    I’m at the very challenging part of the build. Electrical System I realize I need to understand what Isolator I currently have. I do not believe it is the B2B kind. I have read that it needs to be based on the Alternator's Amp Max Output, which even though I've looked at several posts on the...

    Mystery plug/connector near oil pan. Please help identify?

    Can anyone tell me what this plug is for (see attached)? It emerges from a wiring bundle at the top of the oil pan, next to the alternator, and it is just hanging loosely. I have no idea where to connect it. I have a 2008 Dodge Sprinter 2500 (3.0 L V6 Turbo Diesel). Thank you!

    Another LiFePO4 alternator charging question

    Hello.... I'm planning on switching out my AGM batteries with a LiFePO4 so that I can better handle supplying high loads via my inverter. I have 200W solar and having it charge the lithium battery with my MPPT controller is straight forward. Where I'm still having trouble is figuring out the...

    Failed idler / drive pulley & belt. Alternator to blame?

    I was driving at 45 mph in traffic the other day and heard a horrid squeaking noise. Being on a road with no shoulders and heavy traffic, I had to continue on and wait for a safe spot to pull over. The sound was a VERY loud squeaking and it mysteriously went away. Of course, the battery light...
