I have no flashers working now. All other solenoids work. I checked the 43vdc 3/4 amp fuse and it’s good and getting 43vdc. I checked continuity from the transistors to the other side of each string so that not an issue. I went to each string of bright lights, flashers, and had 43vdc or 20vAC at the start and each point through the string so no bad bulbs or plugs. The only issue I can think is the 4.ohm resistor. It has 43vdc coming in but on the other side if I test voltage while touching a grounded bulb to it, added load, the 43 goes to 0. Bad resistor?

Easy to check with a multimeter...

I put it on the lowest ohms setting and it was open, I kept moving it up the scale another 3-4 settings and kept getting 1. On the last few it was different. Not sure which setting I should use and what it should be

Quoted from Armyaviation:

If the resistor is 4 ohms spec, put the multi-meter on the 200 ohms scale. The meter will be able to read resistance from zero to 200 ohms. Any resistance above 200 ohms will not be readable and just show up as out of range ("1" in your case).

BTW measure the resistor with the machine off, otherwise you risk damaging the multi-meter.

Turns out it was the ceramic resistor
