Voltage regulator

Is it O.K. to put my voltage reg. under the seat with the rest of my electric parts or will it create a heat sink?

Yes but.

You will need to increase the wire size of the main BATTERY wire at least (1) size due to the increased length.

Electronic regulators may have a heat sink (Aluminum fins etc.) that helps cool the solid state device that regulates the current going to the battery.
This may require a small fan to keep the air moving around the regulator.

Well that's out. I don't have any room under the seat for a fan.

See attachment for small fans.

Or

You could make a larger heat sink with a piece of aluminum plate about 10"x10"X1/4 " thick . The heat sink on the regulator must be thermally contacting the plate. Use thermal grease (Rat Shack) between the regulator and the plate.
Mount the plate on spacers so that heat will dissipate from both surfaces.

Doc here,

You can use a Muffin Fan From a Computer MPU or case Cooling, (about 6 x 6 by 1 inch thick) .

Provides very good cooling, and MOST are 12 VDC..and cheap at rat shak or FRY's like $6.95..
