New guy to forum, hope I am doing this right. I have a 93 winnebago brave and every time I apply the brake I blow the fuse. Could it be the brake light switch or do I just need to start checking for bad wire also if I turn my turn signal on while the brake pedal is applied it will blow the fuse for the turn signal. The turn signalswitch has been replaced and they worked fine,they still work until the brake is applied. I have looked at the wiring in the steering colum but did not see any pinched wires. If anyone has any ideas I would be grateful......Thanks in advance for your help...

I think the first thing I would do is remove the bulbs and see if the fuse still blows. If it doesn't then a bulb has shorted (rare but I have seen it happen). If it does take a good look at the sockets to make sure a center terminal isn't shorted. Then I would start looking for a wire shorted somewhere.

funny you should mention this today.

just yesterday I did a 3-point turn and backed up into some brush...
this stirred up what the RV world laughingly calls a "wire harness" and caused my R tail/brake/turn lights to stop working.

I managed to fix mine by crawling underneath and looking at the trailer tap connector and wires... and opening both lamp housings... inspected bulbs... and then pulled on all the wire to look for obvious damage...

Then I just stuffed it all back in and wound some tape on the trailer connector wires to tie them tighter to the hitch and guess what? the tail light was working but the dual filament bulb was not lighting.

Had to open up the R housing again and replace the dual filament bulb. BFD.

Lesson on a 17yo anything: EVERY single wire and connection and routing and fastener related is suspect. Dive in and check them over, look for problems (there will be many), clean exposed connectors, secure all. This approach will apply to all other systems as well.
