Dash Fuse Box Help

[Paul]

I have wired a V1 to the dash fuse box location C913 which I understand is “Option Acc 1”. I am getting a 12V reading on the volt meter, but when the V1 is connected the voltage drops to 1.435V. I don’t understand why the volts are dropping. I have wired the V1 gauge directly to a 12V battery just to double check that the V1 itself is not bad and sure enough it works when wired directly to a 12V battery.

Could the fuse be shot that goes to the C913 location? Where is the fuse for this location? I don’t know and would like to check the fuse. I assume the fuse is good since I am getting a good 12V reading, but again I am only seeing 1.435V when plugged in.

I am at a loss, any help or tips would be greatly appreciated.

All I can think of is that you probably have a bad ground. Have you tried to re-connect the ground wire to another point under the dash?

I have not, but will go out in the garage and try that right now and see what happens....

By chance do you know what fuse controls those 4 extra connections locate in the dash fuse box?

Thanks for your help!

C913 is fed from fuse 8, which also feeds the stereo and the cig lighter relay.

C912, fuse 17
C911 lighting switch first position
C910 fuse 38

Thanks Brian. Both the stereo and cig lighter work...back to the garage to trouble shoot...thanks guys

I hard wired my detector to the same connection point, Had similar results. Then I ran the ground wire to the 10mm bolt directly under the fuse box and finally got it to work.
Check to make sure the fuse is in..to see where it is, and the connectors see this post http://www.nsxprime.com/forums/showpost.php?p=391741&postcount=42
Hope this helps...

Hey guys I wanted to thank all of you for the suggestions. I was able to determine that it was a bad ground. I never would have thought this because of the fact that I was getting 12V when measuring between the power wire from the fuse box and what I thought was a very solid ground. After running a temporary ground directly from the car battery, the V1 worked fine. After that I figured it must be the ground. I took the ground that I had made off and reconnected it again to the same spot and now it works. I will monitor it to see if it holds.

Thanks again for all the suggestions!
