There is a small wire that goes to the solenoid, then a heavy gauge wire for ground and another one providing lots of amps. what does the small wire do?
 
Uh.... Matt provides adequate directions with the kit. I believe the "small wire" is power to the solenoid.
 
Small wire provides a low signal to the small electro coil to close those 2 big contact points within the solenoid to give big amperage connections to fascilitate a crank over. Sucks a lot of power to do this. If it was just small wires connecting up to do this job they would burn or melt. Amperage draw.
 
so the first stage is the relay box, triggered I assume, by a handlebar switch. The second stage is with in the solenoid. I am trying to find an electrical malfunction somewhere on the bike for someone. I have no paperwork.
There are some very odd comings and goings of 12V, going to take a while.
 
If you don't have easy access to the instructions, this might be useful. I didn't go into much detail on the wiring because the instructions were excellent, but you might be able to enlarge the pictures to get the information you need.

I think Matt would be keen to know of any potential fault. Perhaps ask him for some scanned instructions?
 
Both CNW and Alton have been very good about backing their product. I need to investigate a bit more before I call him. Something is cattywampus in the wiring...it's possible it has nothing to do with his e-start.
 
@seattle##gs i did some wiring diagrams for the cNw electric start kit that may help you.


There was an issue in a few of the very first kits with two of the wires on the relay being the wrong way round.
However, Matt personally contacted everyone about this to ensure it was addressed.

Hopefully he doesn’t mind me pasting the instructions for troubleshooting here:

If your system is installed and working, disregard the test and info below
Quick test to do on yours:
- There are two equally long black leads going from the battery (ring connectors at the ends) to the relay. One of those leads has an in-line fuse
- There are some numbers when you look at the relay (on the bottom/attachment side)
- # 30 needs to be connected to the lead with the fuse
- You can do a continuity check with a volt meter to see where the fused lead goes to
- If the fused lead goes to the # 30 blade, the harness is good
- If the fused lead goes to the # 85 blade, then the harness needs to be altered as below
- Insert a narrow/small screw driver on the connector side of the regulator block attached to the harness and pull the wire and female connector out of it
- Release both the fused and the non fused leads
- There is a small tab on the female connector and you may have to pry that up a bit before re-installing
- Install so that the fused lead goes to the # 30 blade on the relay
