Hey guys,
I recently added a secondary battery to my 82’ westy. After the mod was complete I tested the new system, which was basically the GoWesty mod that I just fallowed, and everything worked. After the initial, while everything worked, I noticed the battery and check engine light wouldn’t go out after a quick reve of the engine. I got out the trusty multi meter and discovered the blue wire, which I piggy backed off to close (excite) the continues solinode to charge the new battery showed no power. I fallowed little blue all the way to the alternator and no out put.

Did I fry the alternator?

Is my alternator to small for the new 48 amp agm deep cycle battery?

Could I have wired it wrong? Even though I fallowed the videos?

I haven’t read anything about needing a bigger alternator but I could understand if I would need one.

Any ideas out there?

How about a couple of photos?

I doubt the problem is inside the alternator and the stock early alternators are enough for a smaller capacity aux battery setup such as yours.

If your 82 Westy has the 2 fuse holder behind the driver seat then you could have hooked the solenoid control wire to that instead of to the to the blue wire. The solenoids are a much higher load for the blue wire than anything VW ever connected to the blue wire so hooking one to the blue wire can cause issues to appear.
