mkirsch said: (quoted from post at 07:01:46 12/19/09) If you went to NAPA and said, "Give me a replacement generator for a Super MTA," they sold you a 6 Volt generator.

It won't start because you have bad battery connections somewhere...[/quote:ac835a0df1]

My uncle was the manager for the location and I worked on him with it. I remember him asking if it is 6v or 12v system. Could have been misboxed or ???. Both VR and generator came from NAPA.

Didn't start bc the battery was dead. It was WAY below 12 volts on the DMM. Connections look decent with no noticable crud.

I checked the battery this morning (after being on charger) before starting and it was 12.75 volts. I then started the tractor and it was 12.03 volts. Probably dropped when cranking by .75 volts.

What is my next step?

Am I on to something with improper VR or Gen?

How do I check VR?

Will a bad VR still put out some volts and it just happens to be 6v capacity?

How do I check gen?

Should I redo the jumper wire thing? What two terminals?

[quote:ac835a0df1="Pete7"](quoted from post at 18:28:16 12/18/09)...Since you charged the battery with a battery charger and you are only seeing 7 volts at the battery, I'd get the battery tested first.

Sorry, the 7 volts was on the battery before charging and after pull starting with 15 minute road trip at full throttle.

After charging 20 amps for 2.5 hours the battery voltage was 12.75 volts. After cranking with engine running it was 12.03 volts. I am not sure about a tractor, but my pickup puts out about 13.6-14 volts when running.
