temperature guage repair

[Ericster]

we have a 240z. is there a way of repairing a temperature gauge on this car? the gauge is the original and we are sure the problem is the gauge. we checked the sending unit (new) and the wire going from the sending unit to the guage is good. the only problem we found was the smal white wire inside the guage is frayed. is there a way to fix this? if not anyone now were i can get a dual guage like the original.

You can get used gauges on Ebay, Craigslist and the classifieds here, Zcar.com and Hybridz.org.
