CLARK CA-1 Wiring Dillema! What to do?

Postby 17thAirborne » Fri Jan 27, 2012 5:37 pm

I am trying to get the wiring harness ready to start the Clark. I am setting the system up as it originally was with the following:

1. Positive grounded, 6 V system
2. 6 v generator built to original specs by vintage generator shop
3. 6 V coil
4. new wiring harness made as depicted in the TM

I am having problems understanding and figuring out the following:

1. Which side of the ammeter is (+), is it the side that depicts a Charge (+) on the front?
2. The light and ignition switch have a (+) symbol marked under one of the posts. The other one is unmarked. I'm assuming one of the posts is the Feed, but I am not sure which one is it.
3. Wiring coming from the engine harness to the instrument panel that is supposed to be hooked up to the light switch, which post do I use? Do I use the (+) marked post or the unmarked post?
4. When routing the wire from the (-) post on the coil to the ignition switch, which post do I use? (+) or the other
5. The red/white wire going from the ammeter to the light switch, which post do I hook it to?
6. The wire from the negative ammeter terminal to the starter switch, does it mater which side of the starter switch or which post I hook it to?

Just looking for some guidance before I proceed.
Thanks very much.

Here's what i gathered so far from PMs and posts on the CA-1 forum

1. Which side of the ammeter is (+), is it the side that depicts a Charge (+) on the front? It really doesn't matter, reversing the wires will only reverse the reading (showing _ when charging). I'll pick a side and correct if needed.
2. The light and ignition switch have a (+) symbol marked under one of the posts. The other one is unmarked. I'm assuming one of the posts is the Feed, but I am not sure which one is it. (+) is the feed side so send the wire from the ammeter to the (+) post. The other one goes to the light. Again, Its just a switch so it reverses on and off directions of the switch.
3. Wiring coming from the engine harness to the instrument panel that is supposed to be hooked up to the light switch, which post do I use? Do I use the (+) marked post or the unmarked post? same as answer 2
4. When routing the wire from the (-) post on the coil to the ignition switch, which post do I use? (+) or the other? use the (-) post
5. The red/white wire going from the ammeter to the light switch, which post do I hook it to? The (+) post
6. The wire from the negative ammeter terminal to the starter switch, does it mater which side of the starter switch or which post I hook it to? Hook it to the same side as the battery (-) is hooked up so the flow can go to the battery to charge it.

The final question, not originally posted was how is the circuit for the ignition switch completed? Joe at Vintage Wiring stated that there should be a feed also from the (+) post of the ammeter to the (=) post of the ignition switch. He is going to make that ans add it to the CA-1 kit. When i get this all rearranged, i'll take another photo.

Upon consultation with others, I have redrawn the Clark wiring harness connection diagram. I forwarded it to Joe at Vintage Wiring of Maine for a QC. I'll post his response. I hope I am 100% correct on the final product. The graphic of the red wire with white traces is to provide a feed to the ignition switch. Joe is building that and will add to the harness kit.
