Charging question??

[slammedyota91]

Hey guys, first off thank you to all and any who can help me. Just a real quick question, Im re setting my timing gear, and saw I have a wire not connected coming from the alt to the battery side of the engine bay.
I have a Volvo AQ130C engine and looks to be a stock alt? also looks like its externally regulated... If Im wrong correct me please
I have 4 terminals on my alt. One RED which has a thicker red wire coming off going to I think my battery positive post then a lil terminal right next to it with a think black wire coming off it going to I think the regulator?..

Then I have this other cluster of wires (2) Blue and (1) thin black one, One blue wire is crimped into a white one...

The other blue one, I couldnt tell where it went. The white one leads to the battery area/starter area but isnt connected to anything, Also has a ring terminal

Does it go to the positive post on the starter? or?... switched 12v? is it the igniter/exciter for the alt? Thanks again. The boat is a Glastron V164 '71

Re: Charging question??

Oh yea,and the alt. is NOT charging without this wire hooked up... or the alt is bad.. But either way.. not charging

Re: Charging question??

its pretty hard to say what the wires are for. You can download the service manual which has the wiring diagram for your engine. Trace each one to try to make sense out of it.

The manual is in the adults only sticky under Volvo Penta Info.
