Dennis Carpenter Voltage Reducer
I am looking in MAC's Catalog at a Dennis Carpenter Voltage Reducer-Reduces 12 volt to 6 volt-Dash Gauges for $35.00 (SKU 66-62256-1) The only problem I see and it may not be a problem, is that it shows three gauges: FUEL, OIL and TEMP. My third gauge is a volt meter gauge for the battery. The TEMP Gauge is a mercury thermometer gauge on my 1939 Ford Deluxe Convertible. Will this device still work and what will my Batt gauge which is the third gauge in my cluster show? Thanks for y'alls help.

Re: Dennis Carpenter Voltage Reducer
You should be fine. If you didn't wire the batt gauge it would be pegged from the 12 volts. If I remember right there is one wire on ignition switch marked gauges and this is the feed for the three.

Re: Dennis Carpenter Voltage Reducer
When I converted my 40 to 12v I used a CVR (Constant Voltage Reducer from Ron Francis) to reduce the voltage to 6 V for the FUEL, TEMP, Oil gauges. In order to get the BAT. guage (which is really a volt gauge) to read accurately I isolated it from the other 3 gauges and used a 60 ohm reducer to reduce the incoming 12V to the BAT gauge to 6V. Read post #6 here.

Re: Dennis Carpenter Voltage Reducer
Curiosity makes me ask this question. If you went to 12 volts, why did you reduce the lead going to the volt gauge (voltmeter?) so it reads 6 V? Not being familiar with the gauge in question, is it because the gauge will not read up as far a 12 volts? Or was the gauge really an ammeter? ( Quote:

Re: Dennis Carpenter Voltage Reducer
The reducer should put out a constant 6 volts. This is fine for gauges that need 6 volt power (not the sense line for say fuel). Hooking a 6 volts input to your voltmeter should show a constant 6 volts.

The unit mentioned may be a solid state unit but it's hard to tell with the way it is potted. |
