Most would like somehting that heats ASAP, like a heat gun, problem is, it's not effective at heating the critical internals which is very important when they are new. After the first 2 gallons you can relax the heating standards somewhat.
My guess is you are using the battery to power your starter box along with the Comp Heater, yes?
Yes, That was the plan. As far as dropping the voltage, is there a cheap voltage guage that would do this?
