78 spitfire 340 stator issues im thinking

Post by roblarss »

Just picked up a 78 spitfire 340. Stator was out of it and im thinking by the measurements its bad. Does anyone have the ohm readings for the coil? Did some searching but im not sure which sleds have the same coil to get the right numbers.

blk/wht to blk/red - 1.7 ohm
red/blk to blk/red - 160 ohm
light coil is about 2 ohm so im sure its toast but i should be able to test the sled with this one out if im reading the diagram correctly.

I havent seen a stacked coil setup like this before. Im assuming the spark trigger is blk/red - blk/white? Looks to have a new CDI and the old one as well.

Thanks

I guess i answered my own question. I soldered the coils back together as the assembly was all apart and it sparked. Im thinking it was parked for years due to assuming the stator was bad. All the wires to the coils had the insulation flaked off. Some heatshrink/epoxy should fix things up.
