Hey guys,
I've just about got my Quest alternator mounted and ready to go. Just waiting for the heim joint tensioner to arrive.
Since this car has sat for so long and had charging issues in the past, I am a bit paranoid about the wiring of the alternator, specifically the red/white wire on the actual plug that plugs directly into the alternator. It is my understand that this is for the battery light on the gauge cluster and it is an integral part of the alternator functioning properly. Does the red/white wire on the alternator run directly to the gauge cluster? Yesterday I checked for continuity between the red/white wire on the alternator plug and the red/white wire on the gauge cluster plug (pictures below). My multimeter didn't emit a sound which means no continuity (but it did display a really high number, 1770). Is this a proper way to test this?? Should there be continuity between these 2 points? The battery was fully disconnected, not that that should matter.
I also read that a 12v light can be wired directly to the red/white wire in order to bypass the gauge cluster, if needed.
I checked for continuity by probing both of the wires next to the pink arrow in these pictures:

Any help on this specific topic is greatly appreciated.
