Default Re: 1947 convertible

I thought I had sent another update Tues. night but it doesn't seem to appear, so I will try again.
A good friend and super mechanic came over to look at the '47. He found 2 terminals on the back of the ignition switch body became very hot when the switch was on. Voltage dropped from 6V at switch to 4.5V at the coil. He thought the distributor point might be stuck but a test light proved they were operating fine. We took off the distributor and checked the condenser which tested fine. Points opened and closed but seemed discolored as if they were hot.
Looked for the ballast resistor thinking it had failed and could be the cause for the heated terminals. However we could not find it under the dash against the firewall which is where we guessed it should be mounted. I did find a small metal rectangular box (1/2" x 1 1/2') high up on the firewall. It had 5 wires coming out of it. It did not look like a modern ballast resistor.
Is this it or or can anyone tell me where it is mounted?
