Customer Question

Hey Michael. I have a Fleetwood 2002 revolution 38B. I have no power to my fog lights nor to my leveling jack control panel at the dashboard. I checked both fuses and they're both good. Any idea where to start troubleshooting?

Hi my name is Robert...

Did the fuses have power at all? A fuse can look good but might not have power to it, if the fuse has power I would be looking for a plug connector, many times they will bundle a bunch of 12 volt wires and have a male and female connector, sometimes they can vibrate loose or get corroded, they can be located near the fuse or inside the dash. I think the key here is you have two separate circuits not working so if they bundle the wiring harness with the jacks and fog lights then it could be a loose corroded wire. I might also go to the battery and follow the smaller gage wires make sure you do not have a blown fuse or tripped breaker. As a general rule they would be 18" from the battery. I also might turn the ignition ON and use a 12 volt test light and try to follow the wire from the fuse block. I do not have any diagrams, I might try and get a hold of Fleetwood with your FIN and see if they can send you a print, sometimes they can be helpful. Wiring issues like this can be difficult and a test light should help to see where you are missing the power... Hope this helpssom, IF you have more questions or concerns please feel free to contact me... Robert

I will check with my multi meter in the morning. Everything was working fine about 30 days ago. I recently replaced a circuit board that controls battery charging to both sets of batteries (coach & chasis). I disconnected both sets of batteries before replacing it and reconnected them after completing the work. I did notice some slight arcing when reconnecting the battery cables even thought both main electrical switches were turned off and all electrical lights & assumed loads were off. Could that have caused something to malfunction?

IF the cables were reversed then yes it could have blow a fuse or tripped a breaker. I would really look at that area and follow the cables and make sure nothing is blown. I might get a hold of Fleetwood as well during the week they might be able to send you a wiring diagram which might help you out, IF I had any I would give them two you.

Normally you would get sparks if the inverter was on or you had solar panels....

I am a residential electrician and I was very careful to reconnect the cables correctly. The slight sparking I noticed was similar to what happens when you attach a jumper cable to a battery and it sparks ever so slightly due to the small amount of load from interior lights etc. I'll investigate more in the morning and contact you if I have any more questions.
