No crank

[Ken H.]

Tom,

I think you're going to find one of the battery cable terminals just about
to come off. The heat from a surge of starting current can temporarily
melt enough of the solder in the joint to briefly conduct a little current,
which then re-melts the tenuous connection. I've seen it happen too many
times! Have someone watch each of the battery terminals while you activate
the starter. There was a little smoke from the last such bad connection I
had.

You don’t have a surge protector. High resistance at a connector will cayse that.
Why don’t you try some of the suggestions give you and quit trying to guess.

Ok, will change out battery with another one. Is there any other neg grounding spot to use? The one I have the grounding to is to the block which is
under the engine. It’s a little oily there. Then going from memory it seem to have another cable from that grounding point that went over to the
frame, which appeared to be a attempt to add additional grounding to the block ground. If it is a grounding issue I will run thru all those
connections and wire brush clean them and make sure they are tight. I’m planning on cleaning up all these connections to get good electrical
contact and replacing any wiring or cables that look bad. Any general protocol or procedures in replacement and cleaning of wire or cable and their
connections you guys use?

Thanks,
TG

Tom,

At this point, you definitely need to clean ALL of the large battery
cables' connections. And while you've got each of them disconnected,
carefully examine and strongly tug on the connector -- try to pull it off
of the cable. If you succeed, you did a GOOD thing: found the problem.

The number you asked for is 229 nine thirty-eight 27 ninety-seven.

Somewhere I think Ken B did a nice writeup on GROUNDING. You should read it first. And the engine is the star ground point for the chassis.
Everything goes home to there, the central or star point. And remember when working on any 12V negative ground system, protocol is to remove the
NEGATIVE battery terminal first and reconnect it last.

Do NOT change the negative ground point for the negative battery cable. The engine block is the MASTER ground for everything powered the engine
driven electrical system. Oil on the connection will not hurt anything and is actually beneficial because it retards corrosion / oxidaytion of the
connection. I frequently promote the use of anti-oxidation grease on any connection you have apart.

When we say clean we are talking electrically clean, meaning no corrosion / oxidation on the contact surfaces of the cables. I frequently use
stainless tooth or star between cables to bite into the surfaces of the terminals to make a better electrical connection.
