[TR] I give up

[Denman Mike]

Couldn't the wire be nothing more than a shunt. A shunt, for those not  
familiar with the term as used electrically, is used to reduce the  
amperage through the gage. For example, I have a 65 amp alternator on  
my Marcos and a 30 amp ammeter gage. By using a shunt, I am still able  
to use the 30 amp ammeter. The gage needle (with the shunt installed)  
moves less, of course, with a given change in discharge/charge.
