2005 Sea-Doo GTX no beep, no gauges, no nothing even with new battery

[shagmwp]

We just got our 2005 Sea-Doos out to get them ready for the season. We replaced the batteries since they were on their last leg at the end of last summer. We put brand new batteries in both our RXP and GTX. The RXP started just fine but the GTX does do anything. There isn't a beep, the gauges don't turn on, and start button doesn't do anything. The battery tests find. What should I test next?

Thanks,
Donnie

Begin a process of elimination. Use your Ohmeter and clean & dielectric grease as you go, all cables, wire connectors, fuses male & female contacts. Lots of times I have found fault where the eye is tricked. Battery cable lugs corrode internally and
have to be replaced, or lugs cut off and new ones soldered on and marine shrink-wrapped. Bills86e

:agree:


also... did you hook it up backward? even for a second? MPEM's are known to pop very quick on reverse polarity.
