Rotary laser stopped responding. No light at turn on. Batteries good. Got wet in rain last summer. Circuitboard? How to fix?

Will likly cost more to repair that replace. Sorry, that is the way our society is today....throw away what dosen't work.

The saw is probably OK but the battery is toast. Cordless batteries absolutely do not like to get wet. None of the manufacturers will warranty a battery that got wet. Sorry. Buy a new battery.

Pull distributor cap and dry it off. Dry the wires. Not fixed? Change the spark plug wires.This rotary is wet at a source in ignition circuit.

Hi, I happen to own a van too with the same problem except that I know what my problem is. I can tell you that you have a leak somewhere where the wiring to your lights is getting exposed and wet and the sooner you find the leak, the better. If you let it go too long, something is eventually going to short out and leave you with bigger problems and hopefully it won't be the ECM. So I suggest you turn the garden hose on and give your car a good wetting and follow the wiring from the headlights, all the way back to the harness/firewall. Im sure youll find exposed wires that are wet. Good luck

I would check the batterys first and if they are good, generally there is no way for an end user to fix a laser. I have talked to DeWalt in the past about this and been advised not to open it up. you can try to reset the laser and see if it reboots, sometimes they are so far out they won't turn the laser on.

you have lost ground to the right light unit, good luck

sounds like the rain is getting onto the electronics. let the unit dry out and maybe cover the top part of a/c that is sticking out outside

open it up and shake the sp then leave it to dry

good luck

Here are some simple things to try first for a camera that won't power on. They won't work for every case, but they're worth a try:
