Ground Connection for filter cap Zenith G516

11/24/2011 6:55:02 PMBob E

I've replaced the Filter Caps and need to know where to connect the minus connection. It looks to me that it goes to chassis ground. Would the original connection to the can filter cap that resides on top of the chassis be correct? Or... do I need to find a chassis connection other than the original filter cap can minus connection?
Thanks, Bob E

Bob,

Look at the schematic, the common is B- which looks like a rake, this is not the chassis.

Take the negative side of the new filter capacitors to the original connection of the old capacitors, this should be your common. (rake)

Do not connect the common (negative lead of the filter capacitors) to the chassis.

Luck, Mitch

Thanks,
For some reason I thought that the "rake" indication was chassis ground. :O(

On this schematic rake symbol indicates B- and is isolated from chassis.

A lot depends on who drew the schematic. On this one rake is chassis:

The original filter can probably has an insulator chassis mount. The negative can is not connected electrically to the chassis. You can still use the negative lugs on the old can as a tie point for the new capacitors negative leads. This is already a tie point for the B-

Thanks Norm and Warren. I will use the old tie point on the cardboard "can". It does look to be insulated from the chassis.
