Hi every could someone tell if this saw is negative ground or positive:confused1:

Thanks

I would imagine positive as current flows from negative to positive

This is a very stange question, maybe the strangest one ever. The saw has no battery so doesn't really have a positive or negative earth as such. the earth we talk about is taking the coil kill wire down to the body of the saw to stop the spark and that is about all.

 

Why do you need to know????

Hi spud I wanted to know because I've just got this through the post

And I would like to fit it this weekend. I can't seem to get more than one image attached to a reply:blushing:

Mmmm, I would personally try the negative earth version and just spin up the saw on the recoil with the plug on the cylinder to make sure it is working.

 

I base that on the assumption that the magnet going over the coil will create a positive potential or voltage and therefore the ground will be negative but normally this would refer to wether a vehicles negative or positive battery terminal is connected to the car/bike body which you obviously have't got on a saw as there is no magneto, alternator or dynamo on it.

 

I would imagine the comment is for motorcycles and scooters!

 

You may even find both ways work but go for the negative and test as above.

 

Go careful as the plug can give you a damn good jolt if you pull and it isn't earthed out

Thanks spud I will let you know how it goes, I'm always scared of that spark plug shock.

Cheers for the info:biggrin:
