I am working on a WWF that is having problems with the back panel diverter. The previous owner had accidentally shorted the two wires coming into the 32-1800 coil. This, of course, caused multiple problems upstream. Transistors and fuses were replaced, but still no luck with the diverter. I suspect the coil is toast, but I want to make sure.

I am getting voltage to only one lug, which I have read is a good sign the coil is bad. But, why does the coil ohm out correctly? I get 51 ohms (proper for this coil).

Is this contradictory?

Thanks!

Thanks for the input.

Just did the test. The coil did not fire. Also traced both wires back to the board and have continuity on both.

I would agree. But, is it normal for a bad coil to ohm out to spec?

Thank you for the info!

I think it's time to go shopping

Hi Robert. I did both tests just to be sure. Grounded the transistor tab, and grounded the non-banded lug. No joy. I have measured the coil in and out of the game, with and without the diode (even with and without the wires soldered on). The driver and pre-driver were replaced (Tip 102 for the tip122). All other coils and flashers are functional.

Thanks!

Thank you all for the input.

I replaced the coil, transistor, and pre-driver, they all tested OK with the MM. I assume at this point I should be looking at the 7408?

I appreciate any thoughts.

I completely forgot to mention: now the coil just locks on. I've got the board pulled and I'm going to recheck my work and may just re-replace the transistor and see what happens.

Thanks!

Replaced the 7408 and all is well!

Thank you for the input.
