keg1 Posted September 7, 2014 Share Posted September 7, 2014 This is on my 89 R model. 4 ways work fine unless you start using brakes then they quit shortly after. Like starting down a hill with them on and hit the brakes a few times they quit like the flasher gets hot. I think it has to do with trailer because I tried the tractor with the trailer unplugged and they were fine? It does it with any trailer I pull though. I replaced flasher and light cord didn't help. Any ideas? Quote Link to comment https://www.bigmacktrucks.com/topic/36993-4way-problem/ Share on other sites More sharing options...
41chevy Posted September 7, 2014 Share Posted September 7, 2014 Sounds like feed back through a bad or dirty ground.

keg1 Posted September 7, 2014 Author Share Posted September 7, 2014 Checked ground ok. Found that brake lights also quit working when 4 ways do. Acts like something is getting hot and cuts out but I cant find anything. Also tried another turn signal switch I had and still did the same thing.

85snowdog Posted September 7, 2014 Share Posted September 7, 2014 Just a thought … would the circuit breaker be getting weak . Try a new one perhaps. 2 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/36993-4way-problem/#findComment-258977 Share on other sites More sharing options...

That was going to be my next move if there weren't any other ideas. I bought a new one today( $15) and I think that fixed it. I'll try it more tomorrow. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/36993-4way-problem/#findComment-259131 Share on other sites More sharing options...
