Proform 850 dialing it in closer

RMA is something like Return Mail Authorization.
Since they can't figure it out, ask.tell them the next logical thing is for them to check it internally.

Radio noise. Ugh - Not my area of knowledge. OK - maybe. What is on the car that could create electronic noise and/or noisy electic voltage?
He said I would first suspect some electrical noise may be the issue.
Assuming they are the same thing.( radio noise, electrical noise)

As far as the radio type noise, do any of these have wires that come near or run along the wiring for the LM2 ?
As far as the o2 wires, no.
as far as the rest. yes were they go threw the fire wall rubber grommet


There's ways to shield and minimize radio interference, and capacitors can be placed in lines to reduce noise in the lines.
Will Capacitors affect the signal.....like for the tach????

The first thing i had to do, years ago was to install a 10 turn poteniomiter in line with the tach wire from the coil to get it to.

I gave them the ign wire part number and the spark plugs i was using and they never came back and said they were a problem.........


I'm a little dubious because I would think the WBO2 would show noise but would still record. IIRC you said it just stops recording the WBO2 but the other channels keep working like normal. Yes?
When i hit the rev limiter the tach locks up for a half a sec but i think thats normal.
When they had me separator the the tach ground for the LM2, form all the othere ground it fix the intermittent problem with my tps.

nothing in 3 years have fix the o2 from freezing up.


There are some guys on this board who know a lot more about radio noise.
