6368 Posted December 4, 2014 Share Posted December 4, 2014 I found some old posts on here that said you just need to switch the wires on the back...but that didn't work. The gauges are labeled positive ground. This is for my 74 brockway they look just like the mack gauges of the same era but with chrome trim instead of black. They are not like the 82000 series SW gauges in the older trucks. Does anyone know who made these or have part numbers for them in neg. ground. The ones i need are fuel, temp, and volts. Or can i open these up and change them around internally. Quote Link to comment Share on other sites More sharing options...

GreenGiant2 Posted December 4, 2014 Share Posted December 4, 2014 I switched mine in the 761 brock. Also had the alternator switched. I don't think you can open them and switch. Any junk yards close that you could get some from . Quote We the unwilling, Lead by the unqualified, are doing the impossible, for the ungrateful.

6368 Posted December 10, 2014 Author Share Posted December 10, 2014 Went to the junkyard monday and found a busted up mr being scrapped i took out the whole gauge panel. Some of the gauges say US gauge and some teleflex they match pretty good except for the black rings but i know i can put chrome covers on. installed the gauges today and everything works fine except fuel it reads full when i know its empty. By the way, i thought the original brockway gauges looked familiar i went and looked at my old 79 w900 kw and i couldn't tell them apart Quote Link to comment Share on other sites More sharing options...
ThomasGardner Posted December 10, 2014 Share Posted December 10, 2014 I switched my H63 from positive to negative ground. Got my gauges from the following. SW gauges match perfect.http://www.delcity.net/store/Gauges/ Quote Link to comment Share on other sites More sharing options...
