My stepson is deployed and we had his 2006 evo with 58,000 shipped home. After the car sits for a couple days the battery is toast. the wipers, radio and clock still have power to them and will operate like normal with the key out. There is an aftermarket alarm and radio, he replaced the battery last month and I just charged it and added a battery shut off, voltage is 12.7v and 13.9v when the car is running. I was thinking it could be the ignition switch? I’ve already checked the wiring on the left driver kick panel and it didn’t appear that any water is getting and and there’s no corrosion. Any help would be appreciated. Thanks
thanks. The battery is charging. Still weird that the radio and wipers work when the car is off and the key out of the ignition.
Oh, I didnt catch that point that the radio & wipers are working w/the key out. Now that is not right. My EvO's radio, wipers dont come on w/out the engines ECU activated
Wonder if whoever wired up this alarm system has done something causing a parasitic drain?
Start by going through the alarm relays and find any with a wire connected to the center prong. Then pull each relay (with that center wire connected) off of the socket/connector.
Well here is the problem. Lol ****ty radio install.
they had red (ignition) yellow (accessory ) and orange (illumination ) were all connected together. With the harness plugged in the wiper have power the radio and clock without the key in the ignition which I’m figuring was drawing the battery down. There is a factory amp, I know how the yellow and red wire hooks up, does anyone know if the blue wire from the factory side and the blue wire from the radios side and the blue wire from the amp plug all connect together? Also does the illumination wire go to the ignition wire (red) it’s a kenwood. Thanks for all the help
With aftermarket units, yellow is your battery 12v, red is your accessory (hot when key is on I), blue is remote signal to turn on amp, orange dims the CD player when light is on.

On the plus side that's a nice and easy fix lol, but yah that's a pretty terrible install. If memory serves me, you should only need the blue connected to the amp harness.
