It could be a couple of things, bad battery, bad connections, bad alternator. Take the battery remove the cables, and charge it overnight, let it sit for 12 hours without using it, then check the voltage with a digital meter, should read 12.6 to 12.65 volts for a fully charged battery. You might want to check the fluid level if it's a regular lead acid battery. If you check the voltage right after charging you'll most likely get a false high reading(12.65 to over 13.5 volts). Secondly, remove and clean connections at the battery, corrsion can prevent proper recharing by the alternator. Last, once the battery has been charged and installed, check the voltage before you start the motor, then start the motor and check the voltage reading just past idle speed, it should go up to 13.5 to 14 volts. If it doesn't then you may well have an alternator problem. Good luck, let us know the outcome. |

Also along with what Erich said check the ground strap at the motor to frame. Bad grounds can cause a lot of hair pulling and head scratching, good luck. |

I had something very similar when I got my Argo. There were so many bad wiring connections due to "field maintenance" by the previous owner that the battery seemed to drain out after running it. I too thought it was a battery at first but did some investigation and determined it was a faulty voltage regulator. I would never see the volt meter on the Argo move, so I initially assumed it was just one of the other things that had worn out on the old girl. I used a multimeter on the engine connections while it was running and determined there was no current at all, meaning the Argo fan would run off the battery and of course drain it. I replaced the regulator and the old battery is still working fine. I suspect that all the shorts in the system had some relevence to the regulator going but I am not a mechanic. |
