Has anyone had any issues with their Stallion overheating? I put a couple hunddred miles on mine today coming back from a Rally and noticed the heat gauge was on hot. Water is good, fuse is good and no plastic is caught up in the fan. I am thinking that it may be the relay switch? I can pull over and let it kool for 30 min and then on my way again pulling my trailer and after 10 miles on the freeway it heats up again. Any suggestions? Of course this happens on a Sunday with no one open to do any consulting with.
