E550 electrical problems
Sometimes when I first start it and step on the brake my backup beeper warning goes on. Most times it stops once I start driving, but sometimes it continues for a while or comebacks back by chance. Doesn't matter where the shifter lever is, park, reverse or drive.
Yesterday it woke up really bad and anytime I used a turn signal or flasher I got a fast blinker and beeper going. Figured I had a light bulb out. Looked around the truck and noticed no taillights. Shut truck off went inside a building with flashers on, beeper was going. When I restarted, beeper stopped and I had right side taillights but no left Drivers side.
Drove back home still no left side.
Have no idea where to start looking. Electrical is not my strong suit.
Any and all help appreciated.
Whatever switch engages the alarm needs to be carefully inspected, connections tested for being tight on their terminals. This might reveal something easily fixed.
Since this is most likely not factory installed the alarm's manufacturer would need to be contacted for the appropriate hook up schematic. This sort of info wouldn't be part of an EVTM's included schematics.
Not too helpful I know but some of these things don't lend themselves to easy diagnosis, especially on a forum.
