Marine-MP… I have a diesel compactor/roller I bought surplus and the seller claimed to have recently put a new battery in it. I started and ran Great…for a week….then became hard to start. (slow turn-over)
I raised the hood to watch it turn over and saw a slight wisp of smoke leave the starter. A-Ha! FOUND the problem… or so I thought.
Took the starter to a trusted starter/generator rebuilder who did his magic on the starter (new brushes, bearings..whatever)… took it home and reinstalled it. (THAT is a booger to do ..it’s on a 4239 JD engine….where the starter sits beneath the exhaust manifold but in a compactor you can only reach it from ABOVE.)
No change. Still won’t turn over. Checked batt voltage… almost 13 volts. Pulled cables and cleaned the ends. Cleaned the ground-clamps. Reinstalled. Slow turn-over. (runs up against compression and won’t turn over any further.)
Took the rebuilt starter off and back to the overhaul shop. The man said it was a STRONG starter…but changed out the piggy-back solenoid anyway. Back to the house and that damn re-installation nightmare again.
Still…no turn-over.
Took the battery to WalMart…they tested it “GOOD”.
On the way home I stopped at NAPA. They tested the battery….declared it had “13 volts” and therefore a bad battery.
“B.S.”, I said…. “13 volts is Good!”
No, the guy says…it’s a 12 volt battery….13 is too much. I’ve got a new replacement in that size for $140.
At that point I figured I had an idiot salesman on my hands and took my battery back and left.
Passing an Auto-zone on the way home I stopped-in. They had the identical battery (Continental Heavy Duty) on sale for $100. Out of frustration,… I bought it and left my old one with them for trade-in.
Took the new battery home, installed it…and that engine has turned-over just fine and immediately started (without EVER using Glo-Plugs even in winter) …for the last 2-1/2 years on that AutoZone battery.
Moral: A battery can test good at one place. It can be misunderstood at another. It can have good voltage …but have LOW CAPACITY due to a shorted cell. This can all be very frustrating…and you can MISTAKE the problem to be associated with something ELSE you’ve recently suffered…. and that leads you down the wrong path.
Sometimes…it’s just a bad battery and a new one FIXES THE PROBLEM.
(I’ve even JUMPERED a bad battery and it still failed to start because the shorted cell still will not pass-thru the good jumper-battery’s voltage.)
Try a new battery.
Hope this helps.
