Positive Ground?
#31
Thank you guys.
1. What can be done on a bench test that can't be done with the starter installed?
As I understand it a bench test is simply putting cables from a battery to the starter
to see if it turns. Would it not turn while installed if power was applied directly from
a battery?
2. I will definitely smack it before removing it to see if that clears things up,

Hey Bud try turning the engine a bit with the fan or a socket on the crank pulley.
If the starter drive is hung in the ring gear it should pop it loose. Rock it back and
forth when ya do this and if ya hear a bang or thump yer on to something. Like worn
out starter bushings. Also when ya hit the starter with a BFH don't get carried away.
It could break the housing as well as damage a field coil. AND Remember the bolts
that hold the starter motor in also hold it together so it will try to come all apart
when taking it out. Like Ross or someone said be sure and put nuts on the bolts
to hold it all together once ya remove it from the truck.

What I did notice is that when I turn the key on the dash lights are bright (normal)and when I hit the starter button the solenoid (if this is the right terminology for the unit mounted on the firewall with the battery lead going to one side and a cable to the starter from the other side) would make a "whirring" sound vs. the traditional clicking sound on my other vehicles. Then the dash lights would go out and not come back on.

It's a good idea to take pics when taking things apart, especially if the parts aren't going to be reinstalled the same day. You should not rely on memory only.
Installing batteries backwards is a common problem. People should pay attention to where the terminals are located.
Another common problem is buying the wrong battery. GM & ChryCo batteries have the terminals reversed.
People buy without paying attention to how their old battery is configured, then unknowingly hook the cables up bassackwards. Then they wonder why the amp gauge needle shows discharge.
FoMoCo: 1955 and earlier: 6V POSITIVE ground / 1956 thru today: 12V NEGATIVE ground.
Another mistake people make is...they install the wrong battery cables. 6V battery cables are much thicker than their skinny 12V cousins.

Ditto but I use 12v yellow top but that has to do with long term storage and no acid. Otherwise as Ilya says any battery that holds a charge will do.

Hello all.
Color me embarrassed. Several of you guys tried to get me to check battery, which I did. What I did not do because I don't have a tester to do so, was check the cranking amps.
I had two batteries to work with - one had 6.7 volts when charged but "44" cranking amps according to the guy at NAPA. He said that was barely enough to spin it on his bench. The other battery had 6.3 volts and did not register any cranking amps at all.
New battery....Floyd's starter worked perfectly and the new battery lasted through several seconds of cranking since Floyd hasn't ran since probably July.
Thank you guys for all your help. To anyone that suspects the battery may be the source of any electrical problems I would recommend testing the amp output either by your own meter or the auto parts store which will do it for no charge.
I do thank you guys because from this experience I learned about the positive ground system and have become quite proficient at removing and replacing the starter.
I am so very glad to be a part of this great community of very helpful people.
