But if it drops below 10 VDC it could be either a starter drawing too much OR a weak battery.Measure the voltage drop across the wire from battery to starter to determine which. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Fwd: OT truck battery
A FLAPS load tester does exactly that, by pressing a button it loads the battery through a loaded heat sink device and measures battery "reserve under load" on the meter... I have one from Harbor Fright that works fine.. low cost, but handy to have handy..

I want to check anything else first, and avoid EMdW if > possible. A voltmeter may be all that's needed. #1 Battery (ideal, post to post) voltage at rest. (13.6-14.2 is normal) #2 Battery voltage under load. Starter is good. But also a high load of somewhat known size. Headlights can work. (if it's less than 9, either the battery lacks capacity or the current draw is really high) #3 Voltage between engine block and battery "neg". (more than 1 VDC indicates there is probably a problem - likely bad connections) #4 Voltage between starter motor and battery "pos" (More than a couple volts suggest a starter that is drawing too much) #5 Optional - voltage between starter terminal and engine block. (This really ought to be batter voltage under load minus the drop of the starter wire as measured in test #4) It is okay to use a long, thin wire to extend a terminal to the meter for one that is out of reach - like the starter. What can really help diagnosis is to have all those readings for a system that works good. But even without that, these should be able to narrow it down to likely culprits. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Fwd: OT truck battery
Thanks y’all some good suggestions. I put in the battery recently so it’s new, but could still be bad I suppose, and cleaned everything and cables are tight but worth doing again for sure.

Do you have a digital multimeter to measure the voltage at the battery's terminals? How often do you run the truck's engine? Recall lead-acid batteries will self discharge over the period of about a month or so.

Re: [MBZ] Fwd: OT truck battery
Remove the cables from the battery and clean them and the battery post.. re-install them using some "battery cable grease". Clean, Bright, and Tight... you are missing one of those three... IF the battery is holding good charge... have you load tested the battery? Most FLAPS will do it for you, for free. Start cheap, clean the cables and check for good ground connection and hot lead connection on the car... then test load test the battery.
