What gauge wire should I use for the solenoid to the starter. Car is a 53, 6V pos grnd. Thx!

Most of the vendors supply the correct cable. The correct length is just as important as the gauge of the wire. Tom

Thanks, Tom- the reaso that I ask is that the car cranks slowly when warm , fast when cold. The battery cables are #1 G, and the starter cable is obviously a smaller gauge. The vendors all sell #1 as the replacement cable

I went to a welding supply with my old 12v cable and he cut me one out of #1 cable. Bought two terminal ends from NAPA and it works great. Based on what Tom and some others told me on this forum. I went and got all my cables replaced with #1 cable. They didn't have OO or O. WHAT a difference. Car starts on a crank and a half. No pumping the gas pedal or choking the carb. Turn on the switch, pull the choke to half throttle and hit the starter button. Vrrrooom. Thanks again guys.

Jim, You can do a v9oltage drop test to see if the problem is the starter cable or something else. Starter is slow, how do I find out why? A slow starter can be caused by: · Low voltage to the starter · Poor grounding of the starter · Poor grounding of the battery · Worn starter bushings · Worn starter brushes · Worn out starter. The easiest to isolate the problem is to check is the voltage drop going to the starter. First we must establish that the battery and its connections are good. 1 Check the battery voltage by connecting the volt meter across the battery posts, NOT the cables. 2 Have a helper crank the starter with the ignition off, or with the coil wire disconnected. 3 Read the voltage. This will be the battery voltage under load. With a 6 volt battery, a good battery will read around 5.2 volts or higher. 4 Repeat the test with the meter leads connected to the cables. The reading should be within 0.01V of the previous reading. If not clean the posts and cable ends and repeat the test. Next we can measure the voltage drop between the battery and the starter. The max drop should be 0.1V per connection (battery to solenoid, solenoid and solenoi to starter) 1 Connect the COM or black lead to the battery cable and the POS or red lead to the starter connection. 2 Crank the starter and read the voltmeter. 3 Good connections will give you a reading of 0.3V or less with the starter operating. 4 If the reading is more than 0.3V, move the red meter lead to the starter side of the solenoid and repeat the test. The reading now should be 3.2V or less. If it is more than 0.1V less than the previous reading, the cable is bad. Tom
