Guys and Gals,

Does any one know the best way to water proof the electrics on a Trailblazer? More specifically, the ignition system. Every time I hit a little water at speed, the machine refuses to rev and barely idles. When it does rev up, it backfires big time until it dries out and then runs normal until the next water hole. I'm going to tear into it tomorrow and need some advise. Thanks in advance!

 

Try Getting A Can Of Silicon Spray And Spray All Of The Electrical Connections That Should Help Good Luck.

 

silicon spray is great, but if you have the time...and the patents, polaris has so many darn little wires, get a jar of vasiline or petrolium jelly, and take the connections apart, and just dab a little of it in each connection, and put it back together. The vasaline stays put, and doesn't wash out

 

Liquid Electric Tape. You can get it at a boating store. I use it on the electrical connections for the speakers and microphone in my diving helmet and have virtually ended corrosion.
We use the stuff on the boat on the wires for the engine trim and tilt. These wires are costantly wet in brackish water, and we don't have any problems.
Another way to seal everthing up is with RTV silicone, all of the Jeeper's that I know, seal everthing under the hood with RTV.

 

Thanks guys,

I think I found the problem. There was a small area of plastic around the coil that pulled away from the metal. The water might have been getting in there and playing havoc with the electricity for the spark plug. I dried it out real well and RTV/Siliconed it. I also cleaned the board while I was there and removed the reverse over ride module.

Thanks for the idea about the petroleum jelly, It saves me from going out and buying a ton of die-electric grease.

Thanks again, all!
