Does anyone who has had their touchpad/"brainbox" fail ever determined if it was the pad vs the brainbox? After 20 years, mine (on 2002 ZX) is starting to act up. Twice last year and a couple times now, the power switch will not work. However, I know it's because of excess heat because it only fails after sitting in full sun with the boat cover on. Morning or evening (when its cooler) it works and it also worked all winter in my garage. I can do the conversion to rocker switches myself, but I would rather keep what I have if I could fix it. Thanks for any input...
