, Dan Stern recommends wiring headlight's to draw on the alternator side ................. I initially was concerned about the ammeter being less informative, but Dan straightened me out and I have now proved it to myself.!
Dan Stern is full of crap. When you wire ANY significant load on the "wrong side" of the ammeter, this immediately offsets the ammeter reading by that amount. In a personal car like we are talking about here, that might not be a problem.
However, in the "real world" such as a fleet situation, taxis, company cars, and so on, if you were to actually have a few drivers who know what is supposed to happen to an ammeter, you are going to start generating trouble calls.
Everybody seems to be leaning towards the ammeter, here. This is only "half" the problem. The second half of the problem is the BULKHEAD CONNECTOR. Upgrading the bulkhead connector is essential. This is what my comments are directed toward re: "fleet wiring" "Fleet wiring" was a factory? dealer? mod which added larger gauge wiring running through the firewall separately.
