Hi, a third party a few years ago (and before my time) came in and converted some of the LPG machines (various older Hysters using the ignition relay circuit) to NG. The wire to the + of the solenoid comes off the coil and is fused after the coil. (When the machine died it had burned up the wire as there was either no fuse or too high a rating, not totally sure). So I put an in-line fuse holder to prevent melting wires. Additionally I had to run a new wire from the coil to the solenoid so there is nothing else coming off that run.

Yes, I did in fact do a "direct to battery test" and that is when I discovered that the solenoid was ok (or so I thought). Then I took it's wire and connected to the 5 amp fuse and it popped it.

The machine is running now, but I'm still perplexed at why I have to put such a high rated fuse in when ohms law tells me that a 2 amp is about right and a 5 amp would give lots of wiggle room (in case of a momentary high current draw upon being energized).

I'll dig up a more capable amp meter and do some tests. I'm curious now!
