This is regarding the st1100 powered Sedamn.......

 

Why does my heater motor have to be on for my tach to work?????

 

Thanks

Becuase your heater motor has more dispalcement than the engine?

 

 

 

Sorry.

I'm trying to work out what an ST1100 is aside from the Honda Motorcycle.

You should check out his build thread... I think you will then understand It's pretty sweet I must say

As for the tach issue, I would check your grounds and clean them off if you haven't already. Aside from that I honestly don't know. That's for sure a brain tickler...

That is pretty funny, i got a laugh out of it at 6:00 in the morning. Im guessing it has to do with a few parts not completing some circuit due to the engine swap.

Allright, I'll go ahead and type it:)

 

It's because you have the tach wire hooked to the blower motor.

 

I'll be out there in a couple of months for the beer.

ah, the RPM of a fan blower motor

I've always wondered what they spin at. Pretty sure mice would rather they not spin.

I would have to study the wiring diagram to be sure on this. But it sounds like you missed a circuit feed when you did the swap.

Blower motor is back-feeding the "key on" circuit that feeds the tach. Atleast that's what I think is happening.
