Does your multimeter measure Ohms? that is resistance. You'd use the formula: voltage = amps x resistance (E=IR)
Do you have access to a battery charger that can switch between 12 volts and 6 volts? Hook it to the heater motor at 6 volts and read the amperage off the charging dial. I would just hook up the Voltage Reducer as the instructions say and try it for a few seconds. If is a resistance voltage reducer, you won't blow it. If the rating is wrong it'll just get hot before it is in danger of melting. DON'T do this if the instructions say it has any transistors or semiconductors in there. When I needed 6 volts from a 12 volt battery, years ago, I'd drive a nail into the lead connector that is half way between the two sets of three cells. Don't drive it in too far. .bill in corvallis _____ From: [email protected] [mailto:[email protected]] On Behalf Of Ken Wagner Sent: Monday, November 07, 2011 3:21 PM To: [email protected] Subject: [old-chevy-truck] voltage reducer Hi guys. The after market heater didn't work when I got my '52- 3100. Somewhere along the line someone changed the system to 12V. I cleaned it up to see what repairs were needed. I hooked it up for a split second to 12V and the motor runs but I assume it is 6 volt. I purchased a Voltage reducer and the instructions clearly state that I must determine the amp rating for the accessory to make sure the reducer will do what is needed. (the reducer is designed for 1.5 ohms at 4amp max load) How do I determine the amp rating? Although I have a multi meter, I only know how to read voltage or continuity. Any help is greatly appreciated. Thanks Ken Wagner [Non-text portions of this message have been removed] ------------------------------------ Ole Chevy and GMC trucks rule!
