I took a multimeter and tested the wires to see if any where getting power, I know ones a ground but only one was giving off power out of the four, not sure if it should be two or just one. Any ideas on where/how to find the fuse or did I just do shitty electrical job? Thanks!
A pic of your wiring connections might help us help you decipher the 4-wire connection?
You removed the heater to install flooring but did you or how did you re-attach the heater.
Most 12-24 volt systems use the (heater in this case) frame of the appliance bolted or connected to the bus body/metal for the ground connection. But i have never had a 4-wire unit? to deal with?
Pics would help us help you troubleshoot.
