Hey all, couple questions as I'm a newish 79 warrior owner. Strobes stopped working late this fall, though it appears only when it started getting cooler here in Iowa. They have worked on some of our 50 and 60 degree days, but don't seem to at night or on the colder days we've had. First question, am I correct in thinking power pack is the issue? I have had an A&P unplug and clean with some contact cleaner to no clear success. Second, my unit is the HDACF unit. What is the difference in the ACF vs the HDHCF power supply? Could i install the HCF if i found a newer used one? Lastly, if i were to go to LED at this point, my understanding is that I don't need a power supply. What would I need to go that route? Thanks for help!!
