my Tuck is 6 volts, i installed heavy gage copper battery cables and connected the ground to the bellhousing.. per some suggestions on post. i really didn't expect it to make much of a difference in the cranking ability but thought i would give it a shot IT IS AWSOME!!, the truck cranks over great now.. no more of that slow painfull turn over.. wondering if its actually turning over fast enough to start. should have done it years ago... I little pricy for that cable but well worth it. now I am not even considering switching from the stock 6V
same here I did the same thing last year and it has really helped in cranking and I believe in charging also. I once checked the cables after a ride and they were warm to the touch near the connections.
Proper Battery Cables Glad you tried it , this is one of those very basic things they don't teach and after 50 years , someone has prolly changed the cables due to corrosion... Remember too : the ground cable MUST be connected to the drivetrain , not the frame ! . Folks who have 12 volt systems and / or high compression V-8 engines will also receive great benefit from using Group #1 size cables ~ especially on hot starts . If the ends are warm where they bolted to the frame , take them off and wire brush both sides until shiny them smear some wheel bearing grease in the joint before re-attaching . Never , EVER use dielectric grease anywhere but the spark plug cables , it's an insulation on low current applications .
