Hello, Happy holidays. I was messing with the flathead in the welder yesterday again,and almost got to fire up. After the last attempt when it almost started but when I tried again it seemed like the battery died. I think I fried the starter solenoid. Problem one. This welder is al set up with gauges,starter button,fuel primer,it has a block heater etc. The starter button was sitting there but no wire attached to it. How does the button work? Just grounds the wire to the relay? Problem 2. When I hook the battery cables it automatically spins the starter, does the starter button(wire) have to do anything with this? Problem 3. I think I fried the starter relay, could I test this by hooking the battery directly to the starter? Thanks in advance.
I would check the connections and grounds. The wiring may be too small a gauge or corroded. Check all the connections and wire. A simple clean up can do wonders. That looks like a simple push button starter switch from like a Ford F1. You may want to look at a wiring diagram from one of those.
Sorry,I bypassed the starter solenoid,hooked the battery directly to the starter and it fired up,sadly I couldn't keep it running. Bad fuel pump,bad primer pump and God only what other issues are hiding.only thing I can do is try.
As I said before,the flathead fired up and started ,and ran for a few seconds,,then it didn't start so I took a brake from it. I just looked at the primer pump and it's a 6v.. Ooooops
In my very limited experience, the diaphragm in the fuel pump was torn, and that was a long time ago.
