1958 F.W.D. Posted September 27, 2022 Share Posted September 27, 2022 Check the amperage required to run that heater. Bet ya the cig plug isn't enough. 2 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment Share on other sites More sharing options...
Joey Mack Posted September 27, 2022 Share Posted September 27, 2022 I bet 30-40 Amps... I suggest a separate circuit, with a circuit breaker, or Maxi fuse.. Also, be sure the control switch can handle the amp's and make sure what is plugged in has a tight connection, so that heat is not generated by a loose connection on a high amp. circuit.. I'm sure you have replaced a melted heater fan switch or a Ford headlight switch in the past? Hope for more opinion's on this one... jojo 1 Quote Link to comment Share on other sites More sharing options...
bluebonnet Posted September 27, 2022 Author Share Posted September 27, 2022 A 15 amp draw, concerned about the positive ground will it screw things up. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted September 27, 2022 Share Posted September 27, 2022 no.. hook positive to ground, and neg to the line that goes to batt. neg. I have a positive ground truck, and it just seems to me that it is just simply reversed.. Have you searched some of these questions on the web? I did a little research, and that's how I came up with my simple thought's.. to me 'positive ground' is an oxymoron... Basically the chassis carries the voltage, and the ground is direct to the neg. on the battery... I hope others will add to this, and If I am wrong, please accept my apology... Maybe Glenn or Mechaholic, V, F,, heck too many to mention... jojo Quote Link to comment Share on other sites More sharing options...

Popular Post Quickfarms Posted September 28, 2022 Popular Post Share Posted September 28, 2022 The only problem with using a negative ground device in a positive ground vehicle is you have to make shore the case or mound is not grounded 3 Quote Link to comment Share on other sites More sharing options...

Quickfarms Posted September 28, 2022 Share Posted September 28, 2022 I wonder how radios would work with a positive ground since the outer shield on the antenna wire is grounded Quote Link to comment Share on other sites More sharing options...

bluebonnet Posted September 28, 2022 Author Share Posted September 28, 2022 plan on switching the wires and hope the fan runs in the right direction. Thanks all lots of info here. 2 Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted September 28, 2022 Share Posted September 28, 2022 sorry couldn't reply sooner; spent the night in hospital emergency room till 1:30 am. home and doing a little bit better. the answer has been given above the main issue is how an appliance is fasten to the truck. has to be insulated . CB's back in the day neg ground put in pos ground units had to be secured by rubber ties etc. some older brockways also had pos ground if memory is correct. far as the heater, I would install the screw style red/black connectors on lower dash, set up where put the wire end through the terminal hole then tighten connector . 2 Quote Link to comment Share on other sites More sharing options...

bluebonnet Posted October 12, 2022 Author Share Posted October 12, 2022 Will not use the cigarette circuit to power it, will hard wire it with the wiring reversed and attach it to the dash with velcron. there is no metal in the base of the heater. More later. Quote Link to comment Share on other sites More sharing options...
