My NB is still experiencing Hard Starting with a Warm Engine after replacing my failed Starter and installing a new Battery. Any thoughts on why this Hard Starting still persists? Any other areas i need to check on?....THNX
I agree. If you've replaced the battery and starter then I certainly would check the resistence on battery cables....Have you checked all the cables involved for corrosion/deterioration?? Especially the Ground wire where it connects to the transmission... ANY resistance along the wires feeding the starter will have an affect... since this is a high-current draw, the voltage drop will be substantial...
Any tips, procedures on how to properly test the resistance and condition of the Ground Cable? .....ThnxHerm TDI said:I agree. If you've replaced the battery and starter then I certainly would check the resistence on battery cables.
Using your Volt/Ohm meter set the meter to the lowest Ohm scale....Any tips, procedures on how to properly test the resistance and condition of the Ground Cable? .....Thnx
Sorry, Herm I gotta disagree with you here. Imagine that cable with just one strand of wire left connecting the two ends and the rest are completely corroded. Use the Ohm Meter and you get very low resistance since there is that one, good wire.Herm TDI said:Using your Volt/Ohm meter set the meter to the lowest Ohm scale.
Connect one lead to the battery's Neg terminal (black).
Connect the other meter lead to the other end of the ground wire at the transmission bell-housing (make your connection at the wire terminal).
Your reading on the Ohm meter should be reading "00.2" or less
I agree too. A load test is a better indication of the condition of the wire....Sorry, Herm I gotta disagree with you here.

Voltage drop is a better indication.
Voltage drop is easy. Since votage is actually votage potential, if we have the DVOM set to read voltage and put one lead on one of the wire and the other lead on the other end of the wire, and crank the engine. the reading on the DVOM should stay at just about zero volts if the wire is good. A bad wire or one with high resistance will show a reading higher than zero.Herm TDI said:I agree too. A load test is a better indication of the condition of the wire.
But most car owners don't have the means to load test components such as starter draw or large guage wires. Most owners do have a Ohm meter which is better than nothing. But your comment is valid (100%).
But that won't work on a ground lead.Since votage is actually votage potential, if we have the DVOM set to read voltage and put one lead on one of the wire and the other lead on the other end of the wire, and crank the engine. the reading on the DVOM should stay at just about zero volts if the wire is good.

Right. I realized that is what you were talking about and added the rest to my first post there since I think that it is good information.Herm TDI said:But that won't work on a ground lead.
