hot wire to coil

We are not getting any current to the coil from the ignition switch or from the ignition link on the fuse box. We tried running a wire from the battery direct to the coil and the engine started right up. What do you guys suggest to correct this issue?

I assume this is a 67 Olds? Start by checking all the fuses in the fuse box that have power with th key in run such as turn signals, backup lamps, etc. if none of those work, check for power at the pink wire at the back of the ignition switch. if you have no power there, you wont have any at the fuse box.

Before you get to involved, does anything electrical work? Do you have dome lights, does the radio work? Wipers, will it crank? See if you have power at any of the fuses. I dont have a wiring diagram for a Olds of that year, so Im not sure what fusible links protect what circuits. If nothing works, disregard my previous suggestions. A little more info is needed.

This is a 69 442, car ran fine on Friday but would not start on Sat. It will only start by running a wire from the battery to the coil. Every thing else works ok. Thanks

Good chance it is the ignition switch.

If the car cranks when you fire it up you should also have power at the coil (terminal at the starter)
Normally you should have two connections at the coil, from starter (yellow) and resistance wire (pnk/blk)

Id suggest to check if you have maybe a lost connection at the terminal at the starter (yellow).

Ok, Im familiar with the 69 cars. There are 2 fusible links at the horn relay on the inner fender. If all the ignition on fuses in the fuse box are dead, most likely you have a visible link blown or a ignition switch issue. Drop the column, with the key on you should have power at the pink wire, and the heavy brown. The brown wire is the power feed to things that will operate in the accessory position with the ignition, the pink is the power feed to things that only operate in the run position (coil, power windows, turn signal, etc). Do you have a service manual? It will detail the wiring far better than I can here.

Thanks everybody, Matt does the lead going to the + coil consist of two wires (pink and yellow) like my 67 has? I was able to run a wire from the ignition terminal on the fuse box to the coil and the engine started. I will probably install a ballast on this wire to drive the car temporarily.

I have run into the wire from the coil to the points broken inside the insulation so it was not detectable. I replaced this wire and everything worked fine.
