Re: Test Light

It's probably easier to just go out and buy one.

Testing . . . . Testing . . . . Is This Thing On ?

You can use a 194 side marker bulb.

Plug it into a socket.

That’s all there is to it.

No electronics required.


Happy Racing!

Re: Test Light

it is much more accurate to use digital volt/ammeter.sometimes the resistance of test light is too high to allow enough current for memory capacitors to fully charge up and stop drawing additional amperage ergo light stays on and your chasing a ghost.generally speaking anything over 30 milliamps would be reason for concern.test light method is valid on older vehicles w/little or no solid state electronics.
