Gt-700

[chaz]

I’m stumped. GT-700 wash works great......BUT.....

All of a sudden I’m not getting any of my indicator lights to work. Including drive ahead, stop, backup, thank you, and the overhead lights with what step is happening. Otherwise wash works great.

10amp fuse on lite board are good..that’s the first think the book says to check

Thoughts?

Could it be the neutral wire for all the lights has broken or come apart somewhere. I am sure there is probably a common neutral for all lights.

I’ll look again....there are actually several commons....so likely not....but never hurts to check. Tks

Looks like the lighting board is fried. I’m getting quote on new part that I bet will be pricey. In the manetime a couple of relays will activate the drive ahead (green lite) stop (red lite)

I have found that lighting circuits do not play well on printed circuit boards. Ice cube relays are the best way, in my opinion.

Yeah I like the simplicity of the relays. Only problem there’s no easy way for the back up lite and horn if customer is out of position. Also. Likely a bit of a learning curve as customers won’t see all the overhead options lit....but those signs are really only visable as one enters.
