First, here is a picture of my solenoid set up - with small connector facing outwards - it works fine so just let it be?

Here is a picture of the ammeter wiring and new ballast resisistor wiring as set up at the moment. The two wire nuts are my temporary way of connecting a good sized wire to a connector which would fit the resistor connections:

Now I have my ballast resistor in place with the three connection points should I re-route my wiring the way it was originally supposed to be? At the moment I just have to two wires one from the ignition on one side and to the coil on the other side and all other wires connected to my ammeter.

Or, should I just leave it alone as it appears to be working...although not showing much of a positive charge on the ammeter when running.

if it is using the trans safety ground switch, and works facing out.. leav eit.. we have heard of some that are being made that way.

wiring.. I see you are not using the 3rd terminal on the resistor as a wire point... no biggie.. IF it works.

as for the ammeter... look at it like this.. the charge line from the vreg, and the line going to the ballast ressitor hit one side of the ammeter.. the other side of the ammeter connects to the battery ( hot sid eof the solenoid is fine ).

all electrical loads like lamps hit that common load side of the ammeter.. that the ignition is on.

full field he genny to see if the ammeter shows a big charge.. if so. that's good.

with engine off, and key on and points yuo show a small discharge? good if yes.

Lee.......on my eazy starting 6v 52-8N, the solenoid middle terminal faces the engine and goes up the harness and down the panel to sneaks thru a notch in the bottom of the dashpanel to the BIG thumb switch by the tranny shifter where it is GROUNDED.

Yers looks like it is gittin' power from that miss-mash of taped red wires and wirenuts. By supplying power from yer ignition switch, yer bassackwards solenoid is grounded by yer starter copper strip thru yer starter brushes to ground. Starter solenoid will sometimes click and not operate due to brush resistance. .......Dell
