I made a tester with a 12 volt signal light by putting a clip lead to the positive wire of the signal light and another clip lead to the ground wire of the signal light. 2. Next turn the 12 switch off at your fuse box. Then remove all of the fuses (keep up with the position they were in before they were removed) and check to make sure they are all good and that none of them are blown? 3. Then disconnect the ground cable from the battery that is grounded to the frame of the 5th wheel. Now take your tester and connect one lead to the end of the disconnected ground cable and the other clip lead to the ground terminal of the battery. 4. Now you can insert one fuse at a time back into the fuse holder. After you put the fuse back in, go look at the test light bulb. If it is glowing, then that circuit is drawing current from your battery. The brighter the light the more current it is drawing. You can test the circuits one at a time so you can tell if you have more than one circuit that is drawing current from your batteries. That is the way I found that I had a malfunction in my Arctic Pac on my 5th wheel as it would draw my batteries from 12.6 volt down to 10.5 volts overnight with nothing powered by 12 volts being turned on at the time. I hope this helps you to find your problem. Vroadracer Dickson, TNRe: DC power issues- any advice?1.

Vroadracer Dickson, TNRe: DC power issues- any advice?Do you know how to check to see which 12 volt circuit is draining your batteries?Re: Truck shopping 04-07 model years. Advice please.I recently bought a 2007 GMC Classic crew cab long bed with the LBZ engine and a 6 speed Allison. It got 22mpg on the 800 mile trip home at 68mph. I tow a 15,000 5th wheel and it gets 10.5 to 12.2 mpg depending on the conditions. I usually tow about 60 mph as that is near the maximum rpm torque rating for the LBZ engine. You can set the cruise and the tow-haul and it keeps the speed up going up the hills. The engine has 50 more HP than my 2002 Duramax and a lot more torque. I am a happy camper with the LBZ engine package and the 6 speed Allison. VroadracerRe: 2006 Chevy Duramax/Allison Question?I love my LBZ engine in the 2007 GMC Sierra Classic. It averaged 22.0 MPG coming home from Houston, TX when I bought it. I took my first trip pulling my 37 ft Cardinal 5th wheel and I averaged 11.11MPG towing. I followed the suggestion to leave my rig in the Tow/Haul mode at about 62 mph and set the cruise control and let it shift when it wanted to and that seemed to work well in the area where I was towing. It may be a different situation in mountains when I head North in 2 weeks. I am enjoying the extra torque and horsepower that the 2007 has over my 2002 Duramzx.Re: 2006 Chevy Duramax/Allison Question?I thank everyone for your comments on the LBZ model of the Duramax. I found an early 2007 GMC Sierra Classic with the LBZ engine in it and the truck was in very good condition. I drove the 830 miles from Tennessee to Houston, TX to get it and was pleased that it got 22mpg on the way back to TN by me keeping it under 70 most of the time. About 150 miles of that was in severe rain and wind in the left over effects of the storm that hit Oklahoma City. I noticed that it does not lock into 6th gear until it gets to about 62 MPH. Will it be a problem to tow my 14,000 lb 5th wheel in 6th gear out on the open road, or do I need to keep it in 5th gear manually? Thanks for your comments.2006 Chevy Duramax/Allison Question?Recently I read an article in an automotive magazine that stated that the 2006 Duramax/Allison was the best year for the Duramax/Allison? It said that in that year the engine made more horsepower and torque than any other year between 2000 and 2013? This was due to the environmental requirements from the government that begin in 2007. It also said that the 2006 had a 6 speed Allison transmission and got better fuel mileage both towing and empty than other models? I am interested in hearing from anyone that has any experience with the 2006 Duramaz/Allison combination. I would like to know what kind of mileage they get towing an RV and what kind of mileage they get empty on the open road? Thanks for your information.
