I will try to keep this on point...Left home and everything was working fine...stopped at a rest area, turned the MH off, came back and started up again...about a mile down the road noticed the cruise control would not engage...pulled to the side of road and turned on the flashers...alas flashers not working...checked outside stop lights...none...So got out the workhorse chassis book and found two fuse blocks...one in the MH in dash, and one under hood. the fuse for the stop and flashers was on the outside block. changed it and the one for the cruise control and took off...both now work....
HOWEVER...when I turn on the turn signal the cruise now kicks off...and that is my dilemma...any suggestions??

CHEATER! CHEATER FIX FOR THIS...


Slap one of these puppies onto your screwdriver shaft. I'd bet you could not sling-off either the magnet or the screw no matter how hard you tried. Tip, straight from the academy of the one handed fumbler...

He has not fixed it yet and the spray he used will just make things slippery. One just has to sit down over a bucket with the end of the connector inside and remove the little screw that will get lost when checking each end.

I have overhauled my cords many times in 35 years. It is amazing how funky they can get in one season.

Since I am not real handy with electrical kind of things, I was going to go look for a cord...but are you saying I may see the issue if I take the ends off the cord? If it is a ground, how do I know which it is? BTW the turn signal turned for either right or left does the same thing.

Cruse/Turn signal interaction.... I had that too. Turned out a light bulb (In my case.. Well I won't tell you because there are 7 candidates) was not properly seated in the socket,, Re-seated and all work

The seven candidates
Right FRONT, Left FRONT on the MH
Right Rear, Left Rear on the MH
Right and Left Rear on teh Towed
Towed GROUND lead, actually there are two of these, One on the Towed end, one on the MH end (only one on my case which is why I said 7) and yes.

I have had this problem twice.. The firs time it was one of the 1st 4 (I had no towed) the last time was right after I hooked up the towed for the 1st time (the last one). In all cases it was easy to fix.

I will add I did not expect the FRONT turn signal to be the issue. but on mine it was.. Just re-seated the lamp and it works to this day.

It's late and I'm tired. So this is knee-jerk, but let me offer:

Verify that everything is GROUNDED as it should be. So often, we focus on the hot side and forget two things about ground:

1. It's always needed

2. Weak or no ground can cause feedbacks as the current looks for a path home.

Either way...
When setting still (here in a park), I turn on the turn signal...it flashes correctly, then I step on brake and it stops...I then pulled the umbicale (sp) cord out from the MH and the turn signal keeps working...sounds like it is the cord...I had electrical spray and it didn't help...so must as fellow above says...is probably a short..

You may have a short in the toad umbilical cord or either the coach socket or the car socket.

If there is a short, indicated by blown fuses, you could have feedback to the brake line thus telling the rv you are putting on your brakes which would turn the cruise control off. Yes it could be intermittent so take each end of the umbilical apart and open the sockets on the vehicles.

I have some of the electrical spray...could that help...I guess I could check that now that I am parked by taking the umbilical cord out of the MH...Is that what you are referring to?
