How much voltage drop at Starter while cranking?

[JackConnick]

Don felt it was a combination of wiring and starter.

I've already replaced the purple wire, with new #14. I guess I could replace it again, but I doubt that's going to make much difference.

I don't think there's a red wire to the switch only to the solenoid and it's all fairly new. The white wire is what's left to the S term - it's older #12.

I need to take a look again at the circuit again. I just have an ignition switch and a push button.

Pretty much the same issue, lots of cranking, but it did start after a bit. Jack

Is the choke all the way closed?

If your start switch is powered through the ignition switch I still like the 30 amp (DC) rating.

Neil, outstanding logic there regarding the hot wire usage actually indicating suspect ignition wiring!

Jack, before pulling your starter id probably go back and give a real hard look at the ignition circuitry and switch, paying particular attention to your connections. Don is certainly the guru but you may be missing something critical that he would notice in person-- like a wiring terminal connection.

Johns advice to make this top notch is really good and will provide long term reliability that helps your future work.

In my limited experience it's usually smaller things like marginal wiring and connections that are most of my trouble. Unfortunately I don't catch them until after wasting a bunch of time on other things first! ;-)

Just to close this issue

Had the starter rebuilt (now I have an issue with it that I posted).

Then I replaced the "purple" 14 gauge wire with 12 gauge and it starts like a champ.

Thanks for all the ideas and help.

Is this a late or early model starter/solenoid? I'm guessing late model Delco.

I doubt if upgrading that wire from #14 to #12 actually solved the problem. More likely there was a bad terminal or more at the ignition switch, or a faulty connection in a terminal which got corrected by changing the wire. I don't like those switches and have eliminated them from my boat.

Late model Delco.
