Hoping for some help / advise here. PA Fbodies recent post reminded me of something i noticed when i got the car running a year or so ago when i thought it was about finished
I have an autometer tach in the dash gauge cluster, but the dash top has had one screwed in (the original dash console was knackered so the previous owner dealt with it this way). Taking it off meant that there were two nice screw holes and and an impression left, ruining an otherwise pristine dash thanks to a quick fix
I thought ok, we'll keep the tach and then wire it up. I wired the gauge up as per instructions, lights etc work fine. I spliced the tach signal wire coming, so that it had two destinations. What's happening is the gauge in the cluster works fine, but the gauge on the dash reads funny. I can't remember exactly what it was doing as it was a while ago, but i seem to remember it showing higer revs. If i plugged jus the dash top gauge tech signal wire in (disconnected the cluster one) it was normal. So it seems like the signal wire doesn't like to have two destinations? And i'm wondering why that is. If it's sending a signal, it should be able to be read by more than one device. It's not like a fuel sender for instance where the signal wire isn't acutally a signal wire, it's a ground wire with a variable sensor inbetween the ground signal. Same with oil. So i can understand, if you took oil / fuel and have two gauges reading, they might read incorrect. But this one, o'm not sure how to get around this?
Thoughts welcome!
Thanks,
