Hey everyone!
I have a 2005 140" I bought in February of this year and I've never been able to get the espar heater to fire up. It doesn't have the 7 day timer, it is just the heater booster one. I've been trying to trouble shoot the problem and first tested and found the coolant pump to be shot. Replaced that, still no luck. Using a volt meter, the heater seems to be getting power so I moved on to see if it was getting fuel. Nothing. The line is totally dry. Went under the van and found the dosing pump and it has power to the wires but from what I'm reading it goes on a waveform? I don't quite understand it, but either way, the pump doesn't seem to make any noise or do anything when I hit the heater booster button. Is there a way to test the pump? Or is it likely shot? And I've scoured this website and the internet and can't for the life of me find where to buy a replacement dosing pump. Any suggestions?
Thanks everyone!
