ignition switch off, key out, radio and accessories still on
Posted: Tue Jun 21, 2022 1:27 am
Got a head scratcher... Turned off the engine of my '88 M6, removed the key and multiple accessories still are powered, including radio, antenna, wipers, turn signals, and left side warning panel. Ordered and installed a new OEM ignition switch, and it works perfectly. All the key positions seem to power up the proper items and engine starts and turns off with proper key positions. The new switch made no difference to the still powered items. Have consulted the trouble shooting electrical manual, and pulled and replaced various fuses that effect the items that remain powered. Also replaced the 2 power module relays. Pulling fuses for the wipers for example does not keep the other items from remaining powered. Have installed a battery kill switch incase the computer or other silent items are getting unauthorized power. Car starts, runs, and stops normally. Any thoughts would be appreciated? I hate electricity issues!
