Expert Answers about Vehicle Heaters


  • Troubleshooting a Kat's Heaters Custom Fit Engine Block Heater # KH11484 Causes Outlet to Cut Out
  • If you have a Kat's Heaters Custom Fit Engine Block Heater # KH11484 that you referenced and it is causing the outlet of your vehicle to cut out then the problem is that the outlet is getting overdrawn either by the heater drawing too much amperage for the outlet to handle or because the heater has a short in the wiring of it and that's causing the outlet to short out. I would recommend you go over the wiring of the heater looking for any cuts or other obvious signs of a short as that...

  • Is Smoke the From the Kats Heaters Vehicle Heaters # KH24250 On First Use Normal
  • If it only smoked the first time you used the Kats Heaters Vehicle Heaters # KH24250 then you should be fine. If it continues to smoke after every time you plug it in that then something is wrong and I would recommend you remove it as it is malfunctioning. Most likely the heater had dust on it from packaging and now that it's been used once it won't smoke again.

  • Is Wiring of Kat's Circulating Tank Heater Adequate for Amperage Draw
  • I'm really sorry to hear about your vehicle catching on fire. I can't even imagine how stressful that would be. I ran this by a guy who was an electrician in a past life though and for the 12.5 amps that this heater draws 10 gauge wire would be more than adequate.10 gauge wire at 12 volts can pretty easily handle 30 amps so 12.5 amps would be no problem at all. He thought that there must have been a short that caused the fire. This could have been due to an issue with the heater potentially...

  • Blower Fan for Heater/AC is Not Working, Do All Relays and Fuses have to be In Place for It to Work
  • Relays control specific functions so if one is not in place or blown then only the functions associated with it would not work. What I recommend is to consult the vehicle owners manual for all of the fuse and relay locations so you can check the affected ones related to the circuits that are not working to determine what is missing or blown. Relays are harder to check than fuses. The easiest way to check to see if a relay is bad is to use a known working relay in place of a potential bad...

  • Trouble Shooting AC And Circuit Breaker Function
  • The Pollak Circuit Breaker - Cycling/Automatic Reset - 40 Amp # PK54540 is a continuously cycling circuit that will reset itself. The Copper terminal goes to battery and the zinc terminal to accessory. To run a 30 Amp system, you will need a larger circuit breaker or it would trip the breaker each time it started up. A bad circuit breaker may be the issue, but typically an AC unit cannot run off a 12V battery because it simple pulls too much power too quickly. A deep cycle battery may...

  • Transmission Temperature Goes Up and Engine Loses Power on a 2002 Ford F-350 Diesel
  • Any time you add larger tires to a vehicle it makes it harder on the vehicle and more power is needed to do the same amount of work. It happens all the time to Jeep owners. First, if your 2002 Ford F-350 has a stock tow/haul button be sure to use it when towing. The programmer you are using should probably be set to tow mode or heavy tow mode (if there is more than one tow mode) when towing as well. Regarding the transmission fluid temperature I have not seen a vehicle that had a stock...
