MarkV Posted March 22, 2016 Share Posted March 22, 2016 I am at a loss as to how to convert the window pump on my 48 lincoln, do I need a 6 volt adaptor for it? If so which one? Link to comment Share on other sites More sharing options...
Marty Roth Posted March 22, 2016 Share Posted March 22, 2016 Why convert in the first place? Our cars ran just fine the way they were designed - with a 6-Volt system. Keep the contacts and grounds clean. Use the proper sized battery cables - or upgrade to OOO cables You will not need to worry about a hydraulic pump. If you insist on "fixing" something which isn't broken, you'll have a myriad of complicated variances, gauge readings, etc - (but you could just swap out for a 12-Volt starter motor to run that pump, and 12-volt cylinders for the windows, seat, and convertible top Link to comment Share on other sites More sharing options...
MarkV Posted March 22, 2016 Author Share Posted March 22, 2016 Just FYI, this car has a newer v-8 (placed there before I got a hold of it and a messy conversion). All contacts are clean and tight, proper cables, timing set correctly, etc. I would prefer to have it over to 12 volt due to the accessibility of parts. Also the easier starting is a plus. Also, I want to place a hidden radio (12 volt) within the car. I am aware of the 6 volt systems, I have one in my '21 and in my '41 that work just fine. This '48 has always had issues due to the newer engine and the mismatched 6 volt electrical system. Link to comment Share on other sites More sharing options...
60FlatTop Posted March 22, 2016 Share Posted March 22, 2016 That pump should run fine on 12V. Have a good starter shop check it over. An experienced shop will probably agree. Bernie Link to comment Share on other sites More sharing options...
critterpainter Posted March 25, 2016 Share Posted March 25, 2016 One can get away with 12v on a 6v motor for a while, but often the motor will overheat quicker if it is fed 12v rather than 6 volts. The motor may also over Rev and break things. Link to comment Share on other sites More sharing options...
Dandy Dave Posted March 25, 2016 Share Posted March 25, 2016 (edited) 6 Volt starters will last for years with a 12 Volt battery hooked to them. The windings have heavier wire as 6 volt components need higher amperage to work on 6 volt. What usually burns them out is Low Voltage, Or an engine that is in bad need of a tuneup or other work that starts hard. Even 12 Volt starters suffer when cranked too long. In turn, Higher voltage on the top motor should not be a problem unless you run it hard and strain it often, or have something binding in the system putting an overload on it. Dandy Dave!
