DaveThomas Posted September 4, 2019 Share Posted September 4, 2019 Hello, working on a 2013 pinnacle. Currently has no turn signals or flashers, has a new signal switch, all fuses are good, flasher relay is new, and all immediate wiring looks fine. Driving me bonkers. Any help will be appreciated. -dave Quote Link to comment Share on other sites More sharing options...
0 JoeH Posted September 4, 2019 Share Posted September 4, 2019 If everything is LED and you have the wrong flasher you won't have any lights because the LEDs don't draw enough current for the bimetal switch to trip. Need a standard bulb in the circuit. 1 Quote Link to comment Share on other sites More sharing options...
0 HeavyGunner Posted September 4, 2019 Share Posted September 4, 2019 Are you sure about that? I helped put a flatbed on a pick up at work and the flatbed had led lights. They worked but blinked really fast until we changed the flasher.

I'll bet the turn signals on the front of the cab weren't LED. All you need is one tiny bulb to make the system work. Quote Link to comment Share on other sites More sharing options...
0 Mackpro Posted September 6, 2019 Share Posted September 6, 2019 There was a recall on the flasher on about 24,000 CHU, GU and CXU models . You really need to get a flasher from a Mack dealer . The prongs are extra long on the Mack flasher, this is needed as the wire connection are deep in the fuse panel. Standard electronic flasher prongs barely reach the wire connections in the fuse/relay panel . Also check for the wires pushed out the bottom of the panel . Lastly, if all looks good , replace the turn signal switch, we still go through turn signal switch’s in our fleet. 1 Quote Link to comment Share on other sites More sharing options...
