Bugeye Starter Switch

[rossco]

Two switches. One shows continuity when I push the plunger one does not. What do I have?

More details and/or a photo might help, but usually, continuity when you push a button means it's working.

Some switches only provide continuity when activated. Some default to continuity, and break continuity when activated.

The pull switch activates the starter. The operator pulls a knob that is attached to a cable that pulls the plunger that causes contact in the switch. They are side by side on the bench. I'm assuming the one showing continuity is working, the other is not. What say you? Sorry, a picture would only be redundant.

Assuming you have two similar switches, and assuming your starter switch operates like my 1957 Morris ("pull to start"), then yes, if you pull the knob, the circuit will close and bring continuity (and would power up the starter). Which means that one is working.

The new Bugeye starter switch just arrived from Moss. Bridged the terminals with the tester and activated the plunger. No continuity. Is the new switch junk? Don't want to install it if anyone knows for certain. Thanks for answers.

Installed the old switch that showed continuity. Shorted terminals indicate a very, very weak spark.

When you say "shorted terminals", I assume you jumped across the starter switch terminals with a screwdriver or the like. If this is so and you got a weak spark, you probably have a weak battery. I assume your starter was working prior to the operation you are in now.

Bob. Yes to your first answer. I think you are right on. Yes, starter was working. Next I'll add a little tension to the fan belt. It may not be driving the gen properly. Thanks for your quick response. R
