opelsuby Posted December 12, 2006 Share Posted December 12, 2006 I need a new external voltage regulator. The numbers on mine TL1Z-94E 12V 011 It is a hitachi. I can't find this hitachi part. I did find a straight 94 (without the E on the end). Not sure what the E means though. I can't find a cross reference out there for this one. In doing a part search at different vendors, I come up with a gaggle of different regulators. Can anyone recommend one that will work? Brand and part number would be helpful.

opelsuby Posted December 13, 2006 Author Share Posted December 13, 2006 O.k. now I am confused. I looked that one up and it says set point is 14.3 volts. The one on mine has stamped 12v. i hvae no idea hwat a set point is soooooooo, would the one you recommended be o.k.? Why does mine say 12v?:-\ Quote Link to comment Share on other sites More sharing options...
NorthWet Posted December 13, 2006 Share Posted December 13, 2006 12V is the nominal system volatage (as opposed to 6v or 24v, et al). The real system voltage of a "12V" system is 13.2V, and the 14.3 volts should be the voltage needed to charge your nominally 12V system.
