Boost gauge
#24
I opted for a mechanical one. The only problem i have is all my other gauges are electrical. I have them wired threw my headlight switch to come on when i turn my driving lights on. The mechanical one doest work that way..it has to be powered right when the keys turned. So while my other gauges arent lit up..the boost gauge will be.

Thats what i was saying. My other gauges turn on when i turn my parking lights on. The mechanical boost gauge dosent work that way...its lit constantly

Im not talking about the mechanics of the actual boost. Im just talking about the lighting of the gauge. I dunno how i could wire the mechanical to work off my switch like i have my electrical gauges.

I wired my mechanical gauge to LIGHT up exactly the same way i did my electrical. When i flipped the switch..the gauge did not light up. I thought maybe i had a dead gauge. When i touched it to the battery + and - terminals..the gauge lit up.

I'm not sure what kind of wiring setup you have going on. I am just telling you that it can indeed light up with the lights. I have all of my gauges wired up directly to the headlight switch, so when the headlights are on, so are my gauges. There are countless ways and places in your car to make this happen, mine is just one of them.
my mechanical boost gauge has 2 wires....Ground, and positive. How would i wire that to work off a switch? Cuz i wired it the SAME way my other gauges are..and when i turned the switch..the gague didnt light up.

Something is wrong then, because the only wires you have on a mechanical boost gauge are for the light. Wire the light to the same as your headlight switch so it lights up when you turn your lights on. If you can't get it to work like that, then you are doing something wrong...

Now when i touch the gauge wires to a battery..it lights right up.
Shouldnt there be another wire to hook up? Like hook power to power, ground to ground..and then another wire to the headlight switch? Im almost postive thats how the electrical gauges are.

Electrical gauges have 2 positive wires- one for the gauge to work hooked to accessory and one for the light to work hooked to headlight switch, and one ground. Mechanical gauges only have a light as far as wires that need to be hooked up. The light is the same in both electrical and mechanical. Not rocket science here, so I don't know what else to tell you...

So hook it to a 12v ignition positve..and the ground. So boom..you turn the key..the gauge lights up. I dont want it on like that. I want it to it turns on when I TURN my headlight switch on.
Follow me yet?

lol we must be butting heads here. I ran the positve into the positve on the switch. Just like my other gauges. Then grounded it. When i flicked the switch..my other gauges lit..and the boost did not.
#38
why does the mechanical not have an accesory wire like the electrical? I mean that would make sense. That the mechanical is looking for a constant 12v source..rather then a switched source.

It doesn't need one. The little needle moves because of the pressure inside the vacuum line. You can suck or blow on the mechanical gauge port in the back and move the needle. That is the whole point of a mechanical gauge. Nothing electrical about the gauge itself.

Hmm..Yea i guess that makes sense. I just dont see why the electrial would need an extra accessory wire. I mean it already has like 6 wires lol. The power/ground wires...then the wires that run to the sending unit. I'll have to try it again later. I just was almost certain it needed a power/ground/accessory wire, for it to work off a switch source.
