Guest old 52 Posted August 23, 2009 Share Posted August 23, 2009 I just bought a craftsman advance inductive timing light. After reading the instructions, it says you can not use a metal cased timing light on a 6 volt system. Only plastic cased lights. This one says its a chrome housing. I assume this means its metal. Thanks Mike... Link to comment Share on other sites More sharing options...
rsb Posted August 23, 2009 Share Posted August 23, 2009 I would say it has less to do with the composition of the case and more about the voltage requirement of the timing light. I have the light pictured above and have used it many times on my 6-volt car. I just connect the power leads to a 12V battery sitting on the floor instead of the battery in the car.Regards,Ron Link to comment Share on other sites More sharing options...
Guest old 52 Posted August 23, 2009 Share Posted August 23, 2009 Ron, do you also run a jumper from the negative side of the 12 volt to a ground on the 6 volt car? Mike Link to comment Share on other sites More sharing options...
ted sweet Posted August 24, 2009 Share Posted August 24, 2009 no, just hook the light directly to the 12v battery Link to comment Share on other sites More sharing options...
Larry Schramm Posted August 24, 2009 Share Posted August 24, 2009 I like Ron have the exact timing light and use it on my 6 volt truck. Hook the inductive pick up on number one spark plug wire and the two battery connections to a 12 volt battery on the floor. I would guess that the reason that it says not to us a 6 volt power supply is because of the electronics inside of the timing light. I know on mine when hooked up to a 12 volt supply and you pull the trigger you can hear a buzz. This is with the vehicle not running. That is the way that I know the timing light is getting power.

Joseph P. Indusi Posted August 24, 2009 Share Posted August 24, 2009 I have the same Sears timing light also. I used to use a 6 volt lantern battery in series with the car's 6 volt battery to operate it. I ran a jumper from the postive terminal of the car battery to the negative terminal of the 6 volt lantern cell and then connected the red clip on the timing light to the positive terminal of the lantern battery. One day I just connected the timing light to the 6 volt car battery and it worked, just not as bright.Joe, BCA 33493 Link to comment Share on other sites More sharing options...
