Pressure or flow?
For a second I thought I was earning my stripes as a golf cart tech but since then got demoted back. When one of my carts started to sag I took a voltmeter and saw that one was low, and replaced that one. That was easy.
But now I have another cart lagging and all the voltage still reads 6.2-6.3 or better. So now I don't know how to test for flow(amps). The water hose analogy works for me as I am in agriculture so now I am looking at a cart that has enough pressure, but not enough flow? How do I measure that? My radio shack meter has a setting for amps but am guessing I have to lift the cart off the ground now and test it while running? |

Re: Pressure or flow?
Don't even try your radio shack meter to measure the amps generated by a golf cart, it'll melt.
There only a couple ways to measure high current the golf cart controller puts out, ac/dc clamp-on ammeter or shunt ammeter. Both cost money with the shunt type to be cheapest. Another free way is to measure voltage drop. You can do this my measuring the individual battery volts while starting up an incline from a dead stop. This loads the batteries and measures their performance better then static voltage readings. Try this and report back. |

Re: Pressure or flow?
Alligator clips would be the simplest, quickest way.

Re: Pressure or flow?
ok finally had some time to run some readings up an incline:
Cart A - uncharged, some batteries went down as for as 5.5 up the incline Cart B - charged, 3 of the tested batteries read as low as 5.75-5.8 up the incline |

Re: Pressure or flow?
what were the other 3?
sounds like you need a set of batteries and 4ga. cables. |

Re: Pressure or flow?
ran out of daylight to test the other 3, which batteries are bad? all of them?

Re: Pressure or flow?
I don't think your batteries are toasted yet....
Check out some of JohnnieB's posts on batteries under load. They can go quite a ways down and still be good. Too far down and they will be damaged. Under load - 1.75v per cell = 5.25 per batt = 31.50 total pack That is still okay, all of your voltages are above that. That is what ExRay uses for a Warning level on their volt meter. Minimum non destruct test - 1.5v/cell = 4.5v/bett = 27.0 total pack This is the absolute minimum before damage occurs. Knowing how far down each battery goes individually might help point out a weak battery. |
