Cold Blue Posted September 7, 2018 Report Share Posted September 7, 2018 Well, I couldn't get the old oil pressure gauge to work, so I connected an aftermarket one to the metal oil line that goes into the back of the engine block using a rubber brake line with the correct fittings, just to the right of the oil filter, as shown in the first attached pic. Works great. Wish I knew why the old gauge won't work...any ideas? And where do the amp gauge wires connect? When I bought the car, the amp gauge wires had been cut at the back of the gauge, so I don't know where to run new wires and what to connect them to. Help!! I have attached a pic of my flat six. Ain't she beautiful? Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted September 7, 2018 Report Share Posted September 7, 2018 (edited) if the amp gauge is still in the car...you will have to determine if still good gauge...second, if good them split the two wires that are joined and likely taped over in the vicinity of the gauge and connect each wire to a respective post......pull on lights, if discharge is shown...you golden..if charge is shown, reverse the leads on the amp gauge if your car has been upgraded to an alternator..many do not use the amp gauge and instead monitor the voltage system with a volt meter....

Cold Blue Posted September 7, 2018 Author Report Share Posted September 7, 2018 Thanks Plymouthy - my car has been upgraded to an alternator. That's why the amp gauge is not used, huh? So I need to get an aftermarket volt meter and install it? If so, where would I connect it? Thanks in advance, Blue. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted September 7, 2018 Report Share Posted September 7, 2018 on the accessory side of the ignition switch output of 12 volt and a good ground...that way it is only in the circuit when the ignition switch is on... Quote Link to comment Share on other sites More sharing options...

On most cars of that era, the amp gauge indicates +-30. Most all alternators output far exceeds that. And, a voltmeter will actually show your gattery condition not just plus or minus usage vs charge available. Quote Link to comment Share on other sites More sharing options...
