Dawes A/F Gauge blues?

[Subliminal]

Hey all,

I've had this Dawes Devices TD specific A/F gauge for a while now, and I find that it isn't the most reliable thing. Sometimes it reads full blue...sometimes it pulses when I turn the headlights on or something.

I've got it soldered directly to the wire on the o2, and I've got a dedicated wire run to the battery for it, and the other wire is switched in the fuse box.

Any ideas for old Mr. me?

Thanks

might want to run it to the harness side of the o2 sensor, not directly on the o2 sensor wire
check your ground and check your power source

Just out of curiousity, why would I ever want to do something like that? The extra resistance I'd get from it going thru the harness is the reason I took so much time soldering it and running the wire correctly.
