OHC Var settings.

Having problems with an OHC. The compass does not show any direction other than S and SW. THere are Var setting that you can change it appears. Does anyone know which Var setting it needs tobe on, right now it is on 5.

Thanks for any info.

Have you tried these steps from the OHC How-to:

From the map it looks like you are bordering on zone 4 & 5, so you might need to play around with both.

Quote:

There are two possible adjustments to the compass: Variation and Calibration.

In order to perform the Variation Adjustment:

1) Determine which zone of the country you are in from the map below.

2) Press and hold the MODE button until the VAR indicator appears in the display (Approximately 4-seconds)

3) Release the MODE button. The display will now show the current zone number that is stored in the compass.

4) Press the MODE button repeatedly (or press and hold in) until the desired zone number appears in the display (once it reaches 15, the next press of the button will set it to 1).

5) Release the MODE button when the desired zone number is displayed.

After approximately three seconds the display will flash all segments and then return to normal operation.

If the compass seems inaccurate, and the Variation Adjustment procedure did not correct the problem, perform the following Calibration Procedure.

1) Find an open area that is free from steel structures and high voltage lines. An open parking lot is a good example.

2) Press and hold the MODE button until the CAL indicator appears in the display (approximately 8-seconds).

NOTE: After approximately 4 seconds, the VAR indicator will light. Continue holding the MODE button until the CAL indicator appears. If you release the MODE button after the VAR indicator appears, but before the CAL indicator appears, the compass will be in the Variation Adjustment mode.

3) Release the MODE button.

4) Once the CAL indicator has appeared, drive the vehicle slowly (less than 3 mph) in 360-degree circles until the CAL indicator turns off. This will happen with 2 to 3 complete circles.

I love it and if anyone is wanting to do it ill give a hand. its really easy and once you past cutting your headliner your good to. go.

You have an OHC? Did you do that after I was over or did I just miss that?

Nope didn't have it when you were over, just did it last week.

Ahh nice, how'd that go (minus the issue in this thread lol)? I've wanted to do the OHC mod but I just can't see myself cutting up my truck (yet).

Just really nerve racking. Cutting into the headliner was not fun, then worrying about cutting through the roof. But after that just wiring being not too fun in those small spaces. Haven't driven the truck to see if the compass is working yet though...

I can only imagine, cutting through the roof is something you definitely don't want to mess up on. Any luck on getting the compass to work?

Haven't heard from Curtis yet about it. And I will find out on Friday when I drive my truck up to Big Bear...
