6 volt load test

[Al 29Tudor]

Good morning All,
I'd like to know how to set up a load test something like when a battery is tested.
I went crazy for months trying to figure why my car wouldn't start. Once in a while it wouls start right up just as i lifted off the start button. It was as if there was not enough juice for the ingnition while it was cranknig. Finall i found it was the ignition switch which was warm to thetouch after running for a while.
I think if an electrical load could be applied along with the multi meter it would show a dropin voltage while testing the ignition switch.
Thanks for your thoughts.
Al
