Default Turn Signal indicator constant on.

I have a 79 Scout II. When I pull out the light switch to either position 2 or 3...my turn signal dash indicator lights glow constant. If I place headlight switch to the off position they go out. The turn signal operation works correctly in all positions of the light switch...they glow constant in the parking and headlight position...is this normal? I have chased every ground I can locate and have grounded grounds...Any assistance would be great...I also noticed my Hazard light switch will not stay engaged when depressed.

Don't know if the 79 speedometer clusters are the same as older Scout IIs. Picture is worth a thousand words. The little cardboard pieces are taped in there to keep the different dash lights from cross talking (pretty high tech). If you dim or turn off the dash lights, and the problem goes away, it is very likely the some of the tape pieces finally gave up, or somebody was in there and threw the cardboard pieces away. Always try and eliminate the simplest things first when trouble shooting, and this is a quick way to eliminate one possibility.

Thanks Hondo, I went ahead and dissected my speedo unit. It still has the light dividers still in place and in good shape. I have cleaned the contact terminals with light Emory paper and checked the bulb contacts...The factory harness is in great shape with only one repair on the interior light circuit that I can find on the entire harness. The Scout has been re-sprayed with the factory color...so I went to all the ground terminals and ground off any paint that may effect contact...I was an electrician by trade for years specializing in DC...this has got me completely stumped!! Thanks for the quick reply!!

Hondo,
Thank you for sparking the thought process...I went ahead and went simple...I finally fixed the issue after months of hair pulling. The front turn signal bulb sockets were completely corroded and were sending positive signal thru the ground. The tail lights I personally replaced...but when they re-sprayed the vehicle...they over sprayed primer inside the front turn signal sockets...guess it was to much to ask for them to remove...lol

Sounds like you have some feedback. Its usually the result of a compromised ground somewhere. How are the bulbs in the front park lights and rear tails behaving when the HLS is engaged? If you look closely at the bulbs, I'm betting you'll see the bright filament of the dual filament bulb which is supposed to only illuminate for turn signals/brakes...will glow dimly whenever the HLS is engaged just like the dash indicator bulbs are. Perhaps not all of them. Might only be one doing it. You'll have to check them all out. You can even pull those bulbs out and see if that doesn't make your TS indicators go dark when the HLS is engaged.
