I would say it is "typical" of any conversion that the PO hammered there way through a project. My guess with such little information is that there is a voltage drop leading the the fire wall. I would check the wiring leading up to the wall and after. a partial broken fuse able link would cause a drop, of which you will have to find out why it tried to burn. I have take the stance of replacing fuse able links with a heavy circuit breaker and sealing them. I would not replace the link unless there was a problem. If some one stabbed a bunch of wires "looking" for a problem you could lose voltage there. The moisture will seep in and brake down wires through the whole. Which will cause a drop and not let amps through. In the right circumstances this could cause a fire. (unlikely but could)

Yes corroded/broken wires inside the harnes, bad terminals, crimps, loose connections will drop a voltage 0.1 volts here and there and by the time you add them all up, you get quite a voltage drop frome the source to the device. I bet your oltage gauge swings a lot when you turn on your turn signals also.

p.s. iagmc, fix your sig, I think it's suposse to be "felt the heat"

How are you measuring your voltage?? Where is the ground reference point you are measuring from?

You could have losses in your wiring harness or just bad ground connections or poor grounding method.

Try putting the negative lead of a voltmeter on the negative post of the battery and measure the voltage at each one of your accessaries to determine if it is a grounding issue or wiring harness issue. You may find different issues with each accessary.
