Slant 6 Forklift ignition question #3278545 12/27/24 05:57 PM 12/27/24 05:57 PM

Boise Chall OP mopar B Joined: Jun 2009 Posts: 660 Boise Idaho	I have a 1970's Yale forklift with a slant 6 engine running on propane and points ignition that cranks forever to start when cold but starts what I think is normal once it's warmed up. This forklift doesn't have a Mopar starter so it doesn't have the ignition output on the starter solenoid, it has a Ford type of starter solenoid. I replaced the propane system and shot it with starting fluid to see if it's a fuel problem, I really don't think it is. If I temporarily jump a wire from the battery to the positive side of the coil it starts much faster. I only have 1 wire going to the positive side of the coil and one on the output side of the ballast. The ignition looks like a universal replacement and it doesn't have an "IGN 2" output on it. Does anybody know of a universal ignition switch with the "IGN 2 " output or a different way to wire this ignition system to temporarily get 12 volts to the coil for startup so I don't need the "IGN2" ?

I had a universal ignition switch in my drag car with Ign 1 and 2 positions - it has been there forever, and still is, but don't recall the brand name. FWIW, I'm in SW Boise on the Meridian border, if you need wiring stuff or whatever.

Though how it got that nam eis beyond me since Mopar was using them forever. Anyway, the original solenoid was a three stud 6v unit, I replaced it with a four stud one, the fourth stud being labeled I, as in ignition, that is only hot in start and I wired that to the coil + to bypass the ballast in start.

I'm thinking a jumper wire from the solenoid signal to coil plus should bypass the ballast when cranking. But, it might keep the solenoid engaged when running. A diode might be needed.

Sometimes they both will be hot(cranking) but will run off one once it starts. Have seen the ignition power go threw the oil pressure switch also. So no power until it builds enough pressure to trigger the switch.

I've seen the same thing in our warehouse forklifts in the Mojave desert in mid summer on first start up of the day Last edited by Cab_Burge; 12/28/24 01:16 PM.

I've seen the same thing in our warehouse forklifts in the Mojave desert in mid summer on first start up of the day That was my experience back 35 years ago when I worked in factory maintenance. Propane fork trucks didn't like starting in colder weather very well. When it was really cold, we would pull the propane cylinders off and take them in the building for a 1/2 hour, made a huge difference. The fact that it starts easier with a power wire to the coil is interesting. Like mentioned above, I have used the Ford style solenoids that had the 4th terminal IGN on them, that 4th terminal is a crank only battery power source.
