69 which wire powers up the fuse block???

i have a 69 chevelle and it had a battery in the trunk when i bought it, everything just not corectly, so i moved the battery back up front, hooked every thing up and still not right the problem is headlights,domelights,and flashers wont work till you turn ignition on!! with the ignition off the turn signals do work, goofy right, this car does not use a voltage regulator either, i have a 1 wire alt on it connected directly to the battery and a modern msd elctronic ignition, i think i need to know what wire powers up the fuse block corectly, then hopefully i can figure the rest out

Re: 69 which wire powers up the fuse block???

Sounds like someone did a real hack- job.

In factory form, a red 12 ga. wire feeds the entire interior. It enters the bulkhead connector at the firewall on the far driver's side of the connector assembly apart of the forward lamp harness.

The other end is spliced to a 16 ga. black fusible link wire which is connected to the horn relay, which in turns get battery power from a 10 ga. red that runs in front of the radiator to the battery + junction block behind the battery.

-If you don't stand for something, you'll fall for anything.

Originally the fuseable link from the positive battery cable fed the single terminal on the core support behind the passenger's side headlight, then fed from there across under the radiator top plate to the "BAT" terminal on the horn relay, then onto the bulkhead connector.

Re: 69 which wire powers up the fuse block???

hopefully the fuse block wiring was not modified also...
draw your power wires on a diagram so you can refer to them in the future.
need to figure out what/how the previous owner changed the wiring when moving the
battery to rear, i've modified alot of my original harness to make it work how i want.
but i'm still using the fusible links to protect the system same as factory

Get yourself a factory assembly manual. That thing has helped me out big time in the electrical department.

is the 69 wiring color coding the same as a 68? I just picked up a 68 with the same issue and am trying to trace all the headache. I have a Haynes Manual for now starting at 69.

Well the ignition is different so I doubt it.
For 20 bucks you can get a 68 diagram from classiccarwiring though.

The 69 and 68 are different in other ways. I also had the 69 diagram and was also trying to trouble shoot a 68 but there are some subtle differences.

Mine is too old to scan... maybe someone else here has the 68
