Can anyone provide me a wiring diagram of the Heinze coil box?
Would like to use the box I have however not sure of all the soldered connections and gauge of the wire involved.
Tom, I have the correct braided copper coilbox wire. I had to get it made in India; no one wanted to do it over here. PM me and I will fix you up with some.
So far as the box goes, there are only 3 wires. They are arranged inside the switch at 12;00, 8:00, and 4:00 positions. The 12:00 wire goes from the top screw in the switch, down the inside front (switch) panel of the box through a narrow saw cut, then through a small hole and out under the box, across the false bottom panel. It extends out to the contact springs and, since it's a replacement, it can be soldered to the wire that runs across all four of these springs.
When you are actually wiring, it's better to solder the wire here first and go in the other direction, ending up at the switch rather than beginning there.
Clean the tops of the springs nice and bright before you re-assemble the box. Incidentally, the original screw size for the five bottom retaining screws is #5 x 9/16", slotted flat head steel. Most of us use brass #5 x 1/2" or, if the holes are worn, #6 x 1/2" after enlarging the countersunk holes to accept the larger heads.
The wire at the 8:00 position inside the switch goes through the inside of the box in the left hand diagonal saw cut in the same way, out under the box and then through the saw cut slot in the false bottom on that side. It then snakes up through a drilled hole that ends in hole for the mag terminal contact post and is soldered to the head of post's screw. As with the first wire, it's better to begin at the terminals and end up at the switch.
BE SURE to lay down a strip of good electrical tape over the wires on the false bottom, since the wire that connects the contact springs crosses over them both. Heinze originally shellacked two little strips of cloth in place here for insulation, but the modern tape is much better.
The wire in the 4:00 position goes exactly the same way but through slots and holes on the other side of the box for the battery terminal contact.
Please ignore the request i just sent. This more than answers the issues i have. Thanks, Tom Quigley.
