Blackland Dan 08-02-2012 09:45:13 216.114.61.106 Report to Moderator	I tried to hook up my 4230 to 2/12 volt batteries like the guys did in an archived post of Dec. 2011. I hooked up the two 2/0 cables in parallel and I didn"t notice any cranking difference and I fried the posts on the left side batteries. Smoke coming from the starter connection and the positive cable was really hot. I connected the batteries + to + and - to -. I used the original ground to frame and positive cable to starter. What did I do wrong? Scratching my head on this one. Thanks. [Reply]   [No Email]

I think it would be a very interesting TEST if I could get my fellow Texan Blackland Dan to check voltage with the original engine block ground connection attached VS checking the cranking voltage with the added(not factory)starter bolt mounting ground cable and report back to the forum the voltage difference between each. Clean/tight battery cable connections can be the difference between night & day on cranking speed. [Reply]  [No Email]

Reduces the starter's power down to 81% of the 10.0V power level. At 11.0 volts the starter makes 121% of the 10.0 volt power output. [Reply]  [No Email]

Took the starter to our local starter/generator repair man and it tested good. He told me that JD grounds are critical and I should ground it to the starter mounting bolt and make dang sure all my cables were in good clean condition. I cleaned the existing cable really well and hooked it to + on both batteries then a cable from + to starter solenoid. I ran another cable alongside the existing cable and connected to - on both batteries and grounded it to the starter mounting bolt. She really whirls now with no problems. My conclusion is that I had a bad ground and bad cable connections. Didn"t know that would cause all that, but, it did. Thanks for all your help guys. Y"all were right on the money as always. Dan.

Then you answered your 1st statement with your next statement!!!!!!!! Texas tractors have battery post loose /corroded connections same as any where else on this planet but it doesn't get as cold as other places. Your dad's 4230 fit right in with the ""slow cranking history"" of the 4230's from when they were brand new. Once again JD engineers didn't agree with a nuclear electrician(buickanddeere) because later model rowcrop JD tractors came from the factory with two(2) 12V batteries in lieu of two(2) 6V batteries as you recommend just as my 4255. :wink: [Reply]  [No Email]

I didn't have any problems because I routed from the left battery, sitting right next to the starter directly to the solenoid and a mounting bolt holding the starter with everything clean and bright and tight. No doubt it DID make that baby come to life and no longer did I have to use any starting aid in the winter. Jim, I like your candor, Grin. Can't agree with you more. I have one living next door.

This particular 4230 was loosing almost 2 volts on the ground to block connection. Your Texas warm weather tractor may still start with reduced cranking Rpm"s. Have you measured the connection voltage on your tractor? Or just guessing? FYI I never mentioned a 2 cylinder. You're seeing something in Blackland Dan's post I can't find about his tractor electrical system loosing "2 VOLTS". Canadian weather must be affecting your reading comprehension?? Blackland DAN never mentioned trying to crank his 4230 in below 50 degree temperature and since he lives in Texas I think he won't have to worry much about sub-freezing temp's. All he stated was he fried some battery posts. Why should I bother to check my 4255 battery cranking voltage when it cranks fine. I guess you check you daily driver with a volt meter every time you crank it?????? WRONG,continue smoking whatever you're smoking. Irregardless of your massive smoke screen the factory battery ground cable connection is far superior on the 4230 than the JD utility tractors I mentioned!!!!!!!!!!

It still stands that connecting the chassis return cable to a starter mounting bolt. Provides the lowest resistance path. As the problems are on a Texas tractor, there must be a serious electrical problem. What kind of battery clamps arc the battery posts if they are of good quality and properly installed? If trying to parallel the connections onto that weenie little 1/4-20 battery clamp bolt? Yes she's going to melt clamps. Dad's 4230 was a slow cranker and poor starting machine until the high resistance connections were corrected. The battery to battery cable under the cab was rotten. The primary fault was the connection on that corroded/dirty stud. Two 6V batteries would maintain 10.8V to the starter while cranking in freezing weather. [Reply]  [No Email]

It's a vertical threaded stud exposed to moisture and suffers corrosion. What were the voltages at the battery, ground, starter, cable VD drop etc? Or are you just guessing and throwing parts at the tractor? How did you make the double + connection on the left battery and the double - connection on the right battery? Run a dedicated - cable to a starter mounting bolt instead of to the factory joke. As previously stated the starter could be one of the problems. There is a 5KW Denso or the new Delco 44MT that will wail that engine over. Ever tried cranking with the front pump de-stroked? [Reply]  [No Email]

Put a load tester on it when you try to start it and I will bet the starter is bad. [Reply]  [No Email]

The give away to me was no additional rpms when I connected both batteries. Also, wouldn't the additinal current draw cause the overheated cables. I think I'll take the starter in and check it out.
