I found a SpaceKom "miles per gallon" guage in a stack of parts that have been collected over the years. Has anyone ever heard of this? I searched the web and had no hits, whick is very uncommon for my searches. What I need is how to wire it. It has 4 wires, red white yellow & black. Thanks in advance for the help. Randy
I can't find anything either. But I don't see how it's going to work in an automotive application without a vacuum line going to it. Most of the older miles/gallon guages used engine vacuum as a means of measuring engine load.
I am looking for this meter too or parts for it, but I have the wiring info.
Green: Power (12v) to the readout module - turnrs on & off with ignition switch
Yellow: Power (12v) to readout module, on all the time [eg cigarette lighter]
Red: To Red wire from flowsensor
White: to White from speedsensor
This was a great little meter, it reads flow thru the fuel line and speed thru the speedometer cable. Very accurate when calibrated.
Any info on where I can still get one I would appreciate. Worth every penny.
Black wire of transducer & black wire of gauge to ground
Red wire of transducer to red wire of gauge
White wire of transducer to white wire of gauge
Yellow wire of gauge to positive terminal thru ignition switch
The reason I know this is because I have two of these new in the boxes with the wiring directions.
I've had 2 of these SpaceKom MPG meters in the 1970s-80s. One was a black gauge with red and black buttons. The second had chrome-looking silver buttons. Neither of them work any more.
They were pretty useful.
Do you want to part with either of yours??? I'd be interested!
I just bought a twin engine motoryacht that has twin V 6 3.8 L Crusaders in it and plan on mounting the two fuel gauges on the flying bridge of the boat in order to get the most economical fuel burn for any speed I'm going.
hi newbie here, I found this thread thru the wonders of google.
I just got one of these SpaceKom Autocomp 7000A mileage computers, it was with a friend's "new" RV and had not been installed yet. I'll probably scan the instructions and the box and take pics of the parts and put them on my web page some time...just because I like doing that kind of thing...
