I have two relays like the one in the picture. They appear to be in electrical heater circuits. Anyone know the purpose and what controls them? This one is overhead in the front of the coach.
Do you have any kind of switch that toggles between heat and airconditioning? That switch is identical to ones on later coaches that toggle between AC and the big electric element in the aquahot.
Cant find anything like that. I do have dash switches that turn on the front and rear engine coolant heaters (well they would if that old system still worked) I cant find anything that seems to activate the the relays. The contacts are in series with the kick space electric heaters. I hate to disable the relays but I may have to to make the electric heaters work. Cant think of a purpose for them...
i wonder if they turn off the heaters if the AC is on
I have one that turns off ac 1 & 3 when aqua hot electric element is on.
maybe it turns off heat strips when something else is on?
