Stand alone starting battery for generator

I use the truck battery's circut if need be.....Just start the truck

I've done this too. Heater ran the batteries down so low one very cold night that the gen wouldn't start the next morning. I hooked the truck/trailer plug up and let the truck idle for about 10 minutes to start the gen. Worked but I felt that needed to have a dedicated battery for the gen so this didn't happen again. Unfortunately I found that my gen doesn't have a separate charging system so I'd have to have that dedicated battery connected to the house batteries, and that wont work unless I wanted to get involved.....or more involved than I wanted. :)

So after poking around, I found that the gen was only connected to one battery so I connected it in parallel with the batteries to double the starting amps. Haven't had a chance to see if that helped while under the same cold night conditions but if it doesn't and I have to jump the gen with the truck again, I'm going to get one of those portable power supply's and just have it around for just in case. They're handy for many other things anyways.
