Hesitation in Starting Engine

[imgetnab2]

Steve:
Thanks for the information. When the engine tries to turn over, it
turns very slow. I felt the battery connections to see if they were
tight, which they seemed to be, but I didn't notice if any one of
them was hot. I did notice that there was more corrosion around the
back of the battery box than what should be normal. I'll go back
and check to see if it's a bad connection and take a helper with me
to watch the batteries while I start it.
Thanks again!

would turn my key to the "ON" position (not start) and the in-dash
volt meter would read just what it should. Then I would try to start
it, and it wouldn't turn over, acting like the batteries were really
low. The in-dash voltmeter read a horrible drain when I tried to
start it, then come back slowly when I let off the start position.

b/c of the bad connection. I actually heard a "zzz-zzap" from the
battery compartment with a little poof of faint smoke.

the battery top post connections. I found one that was HOT, and
taking off the wire discovered it was terribly corroded, thus the
short in the connection. In fact, it got so hot that it melted the
plastic battery casing around the terminal and the terminal actually
FELL OUT. Of course, then I had to replace the battery.

pops, whatever from the back when you're trying to start it. If your
problem is similar to the one I had, then feel the battery to see if
one connection is hot.

please be specific on whether or not your engine turns slow and then
starts, or whether or not it turns over at all and then fires right
up.

a old bus with an air starter that would hesitate b/c of a bad air
solenoid.
