Marty Roth Posted December 3, 2016 Share Posted December 3, 2016 The radio in my 1954 Cadillac Series 62 has vacuum ports for three (3) hoses. The person who pulled it apart to replace my wiper posts and cables did not note which hose went to which port. Now there is a leak, and the foot button does not seek the next station. Please help to identify hose routing, and/or to point me to a schematic. Thank you, Marty Link to comment Share on other sites More sharing options...
Guest Posted December 4, 2016 Share Posted December 4, 2016 Three hoses, three ports, only nine possible combinations. Shouldn't be too hard to come up with the right combination by simple process of elimination. Link to comment Share on other sites More sharing options...

Then I thought about the antenna, couldn't remember what feeds the vacuum antenna and don't know if the car has one. Link to comment Share on other sites More sharing options...
61polara Posted December 4, 2016 Share Posted December 4, 2016 Marty, The three ports on the radio should be the engine vacuum input and outputs for up antenna and down antenna. I think the foot switch is electric not vacuum. My guess is that the repair guy unplugged the wire to the foot switch and it needs to be put back in.

Marty Roth Posted December 5, 2016 Author Share Posted December 5, 2016 Thank you Dave, I kind of hoped that was the answer, but I had not yet found the documentation. I appreciate your help, and will follow up when I get back to the car Link to comment Share on other sites More sharing options...
Bleach Posted December 5, 2016 Share Posted December 5, 2016 The foot switch is electric, at least it was on my 51 Cadillac. Link to comment Share on other sites More sharing options...
Jon37 Posted December 5, 2016 Share Posted December 5, 2016 My father's '54 Caddy had the vacuum-operated antenna and from the day he bought the car (in 1955) it never worked. Up or down. Just hissed. It was either the left or right control knob that controlled it. You pushed the knob in or pulled it out, to make the antenna go up or down. (Or vice-versa.)

Bleach, thanks - you are correct, and I'll get back to it, hopefully soon. 19 minutes ago, Jon37 said: My father's '54 Caddy had the vacuum-operated antenna and from the day he bought the car (in 1955) it never worked.

Thanks Jon, by the way, we displayed the 1915 Hudson with the AACA/HCCA group at the Hilton Head (SC) Concourse, and then drove it the entire next week at the combined Reliability Tour based out of Savannah, GA. other than the frequent snugging up of the new packing for the water pump shaft, the '15 Hudson SIX-40 Phaeton ran "like a Swiss watch", and is a pleasure to drive at speed.

Mine actually worked. It was pretty cool to see it go up and down so quietly. Link to comment Share on other sites More sharing options...
Bleach Posted December 5, 2016 Share Posted December 5, 2016 I checked my 52 Cadillac shop manual and middle port on the radio is for the vacuum tee and the others are for the top and bottom lines for the antenna. Link to comment Share on other sites More sharing options...

Thanks - nice to know that it could be functional. I have a vacuum antenna packed away somewhere, and will eventually restore and install it.For now I just need to get the radio full functional again, as it was before we started the A/C project, and before we install the repro-Mark IV unit under the dash.

Great - thank you, I'll be sure to check the connections, and to block of the fittings until we get to install a good antenna Link to comment Share on other sites More sharing options...
