Westach needle rise with voltage drop

[OILBRNR]

Anyone with Westach units for fuel or transmission temp experence a rise in reading as additional devices like headlamps, blower, wipers, etc are used?



I have the postive feed coming off fuse number 17 which is for the cluster, and ground is from the bolt just above the kickpanel. I wouldn't worry much about it if it was just a small raise, but it can add up to be pretty significant the more things are turned on.



Thanks

I have noticed the same thing with my Trans. temp gauge only. No problem with the other two. I tapped into fuse # 8 for power and # 5 for lights (I think thats correct). I see a slight increase when turning on the headlights and turning up the ac fan motor. From both off to on there's about a 10 degree difference. Not sure what to do about it.
