1967 1/2 fuse idenifacation

[ggg3988]

Can anybody take a photo of a stock fuse panel and identify what the fuse services. The last terminal or bottom terminal has now power to it and I am trying to clean things up and understand my system. 1967.5 1600. Stock I think. Had the car two weeks can't wait to see some other cars to compare and create some idea of what I should be trying to do

Have you checked the wiring diagram in the techwiki?

The terminals on my car's fuse box are stamped.

I made a table for myself a while back...

Terminal B - From Battery Via Starter (Green / White)
to 20A fuse to
Terminal H - To Horn and Cig Lighter
circuit is always hot

Terminal A - From Alternator (White) and Ammeter (-) (Black)
to 30A fuse to
Terminal L - To Lights - Red and Red/Green
circuit is always hot

Terminal IG - From Ignition Switch and unfused to Ignition Coil (+) via Ballast Resistor and unfused to Voltage Reg (all Black / White)
to 20A fuse to Terminal F - To Flashers (Green) and Washer Pump, Heater, Oil Pressure Gauge, Gauge V-reg (Green/Blue)
to 8A fuse to Terminal W - To Wipers (Blue/ Red) and Reverse Light (Red/Black)
circuit is hot when ignition switch is in "ON" position


Note - Factory AM radio is unfused from fuse box, but has its own 2A fuse in-line under dash from ammeter neg.

I have no power at b terminal or h terminal. Does the battery wire route straight from the starter to the b terminal ?

[bikermike]

I assume you have power at "A" and "IG" and you are only trying to figure out why "B" is dead, right?

If you have no power at "B" then it follows that you wouldn't have power at "H" either since "B" is its source.

So to troubleshoot "B" trace the green/white wire to a 3 terminal connector under the air cleaner that goes to the starter harness. It should be towards the rear carb and firewall.

Is that connector properly seated? If you unplug the connector do you have power there on the G/W wire coming up from the starter? Do you have continuity from the connector back to the "B" terminal? I would try to isolate the fault to upstream or downstream of that connector and keep working your way backwards or forwards from there.

Usual suspects are a damaged wire in the starter harness or an bad terminal along the way. A wire may have gotten close to the exhaust and burned through.

You could run a jumper from the battery to the "B" terminal to test the rest of your wiring downstream of the fusebox, but ultimately you'd want to understand where the upstream failure is.

In the stock wiring, the + cable from the battery goes to the starter where it feeds the the circuit to the 'B" terminal and also the circuit to the ammeter.

Good luck.

Very nice summary Mike!

The po loved masking tape and zip ties (grrrrr). I have gotten down to the starter and found one wire just hanging their not the culprit. Still looking. Thanks for the help.

I have three wires going to the starer plus the battery wire is that correct

As indicated in the wiring diagram

http://www.311s.org/PDFs/1967_5%20%20Da ... n%20false;

you should have the battery cable and 3 wires going to the starter. The 3 wires are the ones in the connector beneath the air cleaner. Note that the wire from the ignition switch goes to a different terminal on the starter solenoid than the rest of them.

Check out this thread for a pic of a starter harness: http://311s.org/phpBB3/viewtopic.php?f= ... ss#p123026

Given that the previous owner has done some re-wiring, you may want to confirm that the wires to the "A" and "B" fusebox terminals have not been swapped. Confirm the colors of the wires going to "A", "B" and "IG" or check continuity w/ an ohmmeter if the colors are different on any replacement wires. Maybe you have an issue with a different circuit that is mis-wired to the fusebox - just a thought.

Also look for simple things like a poorly crimped ring connector at the fusebox. A little cleaning w/ sandpaper on the terminals and ring connectors wouldn't hurt either.
