Dwell meter choice?

[BOBBYR]

Hi Guys
Here's a good one for you.Lets see what answers we can get for this.
Lately,I've been looking for a dwell meter so I can set my points really precise.When looking at certain models it struck me that I have a positive ground electrical system.A common dwell meter is connected to the negative side of the coil,which is the lead that goes to the distributor.Because our cars are positive ground,do we have to get a special or reverse polarity dwell meter to use?That ought to get some interesting feedback.As always,I appreciate your help with this.

No, you are not measuring positive or negative or hybrid.

You are measuring the time the voltage is keeping the points closed on that particular circuit. All you have to do hooking up a dwell meter is make sure one lead is grounded and the other is going to the point side of the coil, or lead from the distributor if it has an exposed post terminal.

You can use analog dwell meters, digital dwell meters, timing lights with dwell meters built in, oscilloscopes, etc.

All you have to be cetain in measuring is that you have the dwell meter set to the proper "scale", 4 cyl, 6 cyl, 12 cyl, etc...
