Hope you guys can offer some info on this. A buddy of mine has this old Cushman. It has a 4 cylinder slant engine with a bad coil. Chasing the numbers, it appears the coil is for a Dihatsu engine. The coil has F-076, and 90048-52057, and the word Diamond on it. E-bay has one but it looks worse than the one on my desk.

This has 3 spade connectors, external resistor. Any idea on either replacing it with a standard coil or just finding an OEM? The 3 spades have me confused. I haven't cut the wiring harness apart as of yet to chase wires, but may have to.

 

How is it driven, points or electronic.

If points, probably any past era 12v external resistor or 6v coil (actually the same thing) would work.

How about a picture.

 

It is points. The owner wants to stick with original, but I'm trying to talk him into using a regular old coil. I'm just not sure what the extra blade is for. I'm betting I can wire a regular coil and then see what doesn't work. Ohming the blades on the original every which way reveals nothing but an "open" no matter what I try using both a digital and an old analog meter.

 

IF THERE IS NO RESISTANCE, coil is bad. with old tractors and my oldies (40 Plymouth truck, 46 ****** jeep, etc.) the third post (positioned at noon)
was for headlights (switch on and off at dash) with a battery system.
yes, 6 volt system. we use to have a sixties Cushman truckster, all parts were replaced through NAPA.....

hope that helps a bit..

 

Quite likely power, points, and capacitor.

Find the capacitor in the original setup. With an ordinary coil, points should ground the negative side of the coil primary. Power goes to the positive post. Cap-zappiter goes to the same terminal as the points. If the cap isn't in the distributor, put it on the coil.

Can you google a vintage service or owners manual for the beast that would have a wiring diagram in it?

<edit> Mom's always right.

 

Thanks for the inputs. Talked the owner into changing. Did however find the original, except would have to order 500 from China. Somehow owner didn't want to do that!!

(Mom is always right) Yup!!!!
