For the record, I did not make this stuff up myself. This is a compendium of years of observations, measurements, failures, and ongoing input. I learned all this from you guys (much from Kiwi_Roy!), 100,000 miles, and twelve Spine Raids. I'm on my sixth generation relay set.
But, it ain't over yet! : Last time I measured the temperature of OMRON G8HN Relay#5, it was ~147ºF. If it is not materially improved with this double rated G8HE OMRON, I will be surprised (and, perhaps, a little disappointed).
At which point, all of the stops will be pulled out . . .
