Kenworth electrical problems

Alastair Glover

2000 Kenworth W900L has intermitten electrical power loss. Stereo loses power completely, blinks back on, resets itself. Lights sometime flicker and jake brake has lost power and flutters from medium to high but on single stage setting seems to operate correctly.

Corrosion can cause some funky issues

Hey buddy, that’s a classic sign of a bad alternator.

Check your ground connections, could be you’re not getting a good bite

I had a similar problem with my Kenworth. It was because of a loose ground wire that was causing intermittent power loss. I had to tighten it and clean the terminals. You should check your ground wires for any looseness or corrosion

My Kenworth had some electrical issues too. It was because of a faulty ignition switch that was cutting off power randomly. I had to replace it with a new one.

new batty cables seemed to fix the problem

Also check the connections on the outside of the fuse panel they are prone to corrosion

Sounds like a ground problem. Also, some of the connections behind the dash panels have bullet-style connectors. Some have short extensions with up to 3 plugs. Could be loose.

+ Check to see if the problem s are on the same circuit or are powered by the same relay, when trouble shooting KW remember that most stuff is ground switched, not hotside switched just to make things fun.
