320BL cat when i turn the key all i get is clicking noise behind the cab checked the batterys they all have 12.75 volts been doing it for awhile where somtimes i would have to turn it on and off 3 or 4 times but would start.Anybody run into somthing like this.
Sounds like a bad cable or connection. Get a helper to hit the starter switch and a voltmeter. You will probably find a point between the battery and the starter where the voltage will show 12.7 volts (with no load), then when you hit the ignition switch the voltage will drop off.
Could a person check it at the starter think the starter thats on there is an aftermarket one.I did look at the cables they look good but maybe inside the coating maybe bad. Would anybody have the serial # of cat starter engine is 3116.Thanks
You can do the test I described either from the starter and work toward the batteries or vice versa. Looks don't count for much with electrical problems. edit: when checking at the batteries put your tester on the battery clamp first, not the battery post.
Odds are its the solenoid on the starter. Have someone hold the key when it clicks, check terminals with test light or tap on it with a hammer. most of the time they are easy to replace.
Thanks guys will post tomorrow as to what I find.
farmerlund is not wrong, though I've found that on automotive stuff it's usually the solenoid, on industrial it's more often cables, connectors or weak batteries. The only way to test is by putting a load on the system. In addition to a volt meter, I make a LOT of use of one of those inductive voodoo battery testers. Not that expensive, but can tell you the actual condition (available CCA) of your battery.
If you don't have a buddy you trust, make up some test leads with an alligator clip on one end and the other end a bare wire end to stick into your multimeter. Buy an extra multi meter and you can do two tests at one time.
It should have 25-26volts at starter right? I don't own a 320bl but assume it should be 24v system.
Yes it is 24 volt I have a good tester for testing battery's have my mechanic come to morrow morning to test wiring and such
There will be one or more relays between the switch and the starter, look for the fuse panel and see if there are plug in relays there first, there may be a larger solenoid style starter relay somewhere on or near the engine also. Not familiar with this particular model though, just speaking generally.
Found the problem was solinoid on starter so i'll pass it along maybe help sombody else that might run into this issue.Thank you for your advice
