new carb ok, now nothing from the starter

Post by timspider »

After a week of digesting everything I could about installing a new weber carb, I got it in this morning. Got the carb bolted down with spacers/gaskets. Made sense of the linkage conversion stuff, got that hooked up and pulling.
Re-connected the battery and cranked her for about a minute, knowing that fuel had to get back in the line, the new fuel filter, and the new carb.
I let it rest for a minute and then cranked a second time, she fired up just about when I thought she would. Idled nicely, revved ok but I had to lengthen the linkage section closest to the firewall just a touch to allow it to fall to idle. Which makes sense since I'd been tightening that for months now, unaware of the missing clip that holds the ball in.
Now all four connections of the linkage are clipped and everything looks to be solid. I turned the car off to fiddle with the linkage for a bit.

made the lengthening linkage adjustment and went to start her up again.
Nothing.
No clicks, no slow crank, no noise at all when I turned the key. Clock is still working and the annoying key buzzer still works full blast, lights come on.
But now it appears the starter is not getting juice or perhaps just quit.
It cranked just fine 30 minutes ago.
Any ideas?
where do I start now? fuses?
this vehicle is a test, right?
At this point, I feel like I'm struggling to get a "C" and the principal is suggesting that maybe I should be held back.

Check that the red wire has not fallen off the male connection on the solenoid. If it's on, try tapping the solenoid.
This circuit is not fused.
You can try removing the red wire from the male terminal and jumping the male terminal to the large wire from the battery.
Make sure car is out of gear! If that does not make it spin, then the starter or the solenoid is toast.

Yes, That "Faston" type connection is a real weak point, I have had trouble with it as well. If you clean the connection up and crimp the connector a little to get a tighter connection it helps a lot.

thanks very much! I needed to bring myself up to speed on the starter anyway.
everything I've done so far has been from the top side. (convertible top, radiator, plugs, wires, distributor, air cleaner, carb, interior/exterior trim)
I guess it's time to get on the ground and get a little grimier along with a voltmeter. Eventually, I will know every square inch of this car, which I love. The journey is a little bumpy, but the acquired knowledge along the way is awesome.

Tim, you should be able to access the starter's wires from the top, they are under the intake manifold toward the rear.
You only need to get under the car to remove the starter.

thanks for that- i've been having a heck of a time just getting a visual on it. partly because I don't know where it is exactly and partly because it so grimey underneath the intake manifold everything is one color. When I reached down to where I think the starter wire harness is, just under the manifold on the firewall side, I'm able to grab a small bundle of wires that seem to be in a boot- I can't see any of this stuff so I'm guessing. I did see the thick green cable that should go to the starter but having a hard time wedging my head far enough into the engine compartment to see where it attaches.
I'm thinking those are the connections that need to be cleaned, but as of yet, I haven't even been able to see them.
As obvious as this should be, does anyone have a picture of the wires connecting to the starter?
I know I'm in the right neighborhood now, just need a little clarity about connections if possible.
Once again, thanks so much to everyone for sharing your knowledge.

Don't have a pic sorry.
There is a red cable much smaller than the green one that goes to a separate (but close to the stud where the big green wire goes) male terminal.
Try using a mirror.

Trying to post a pic that will display here. After moving my crankcase vent hose and then washing 37 years of grime of the wiring boot I found a red, a green, and a brown wire. Is the rusty thing on the right the solenoid housing?
Next step, disconnect battery, peel back this boot and clean all contacts, correct?
If this pic doesn't post, ill try via the direct link.
Thanks csaba!

As long as the nut holding the other wires is tight, you only need to worry about the connection of the red wire, which goes to a separate male terminal (the wire has a female end).
