I just tried cranking the engine by jumping the fender solenoid without the ignition on. Didn't want the glows to be drawing power... Slow but I'm sure it would start if needed. So I tested all the cells again...
The cells at the positive ends of each battery shows they are shot.. They test very low onspecific gravity 1175.. Almost wont float the bulb. The others show in the green and very close to the same gravity number 1275. So Its looking like the batteries are gone but still on an 85 month warranty.... I just don't recall when I bought them. It may have been 5 years ago.... Thats not worth the warranty to me... Group 31 is going to do the trick for me. The battery tray will be a jobto lower and the cables on the positive are already lug ends. I just need to installlug ends onthe negative cables. I may cut the hood undr the top sking and lower the battery trays... Anybody got a demension of the group 31 batterys.I know they are longer andtaller but thats about all I know.

I paid extra on ebay for this and the seller sold it to me putting out 180 or 200 amps... Can't recall but I know it was more than a stock alternater. At least I can just look into the windings now and tell if they are enough to handle high amperage. The trick is look at the wires. If you see groups of two off the coil then its a low or 130 amp.... If you see three wires and they are larger gauge then its a high output alternater. So Now my starting issues are the batteries or the starter.... I'm leaning towards the batteries. Read back a few posts andyou will see one cell in each battery is very low compared to the other 5..... 85 month batteries shot with no more than 60 months on them... Upgrade time thats for sure... I'm not the kind of owner that buys a lifetime type warranty. I realize those are a pay it once but replace it over and over...I don't make time for that kind of warranty... Who knows when its going to crap out on you down the road....
A 12" piece of 3/0 wire to the starter is too good to be true. I even has the thought of building an enclosure and insulating them. Some heat tape in the winter and dual time clocks, one for the block heater, one for the batteries. The truck couldn't help but start on the coldest day
