On ur train horn compressors and ur plow power circuit ru guys using relays if not I'd try putting one in. I had the same problem when I installed my HIDS no relay I put a relay in and no more freezing
Maby when u lay on the horns it scares the szit out of ur edge and that's y it's freezing ..... When u blast the horn does the compressor come on right away?? Does it freeze just if u lay on the horn or does it freeze when the compressor comes on??Yea i'm running my compressor with a relay.
