BLOZ UP Posted November 7, 2011 Share Posted November 7, 2011 Anyone have the resistance vs temperature values for the L28's temperature gauge thermistor? I just need 3 pairs. Quote Link to comment Share on other sites More sharing options...

BLOZ UP Posted November 8, 2011 Author Share Posted November 8, 2011 (edited) Thanks, but I'm looking for the dash gauge sensor's values. I'll suppose it's not so hard to measure anyway. I'm trying to get the stock gauge to work with a VG30ET, and I'm willing to bet the curves are similar.

macambra Posted November 8, 2011 Share Posted November 8, 2011 The curve is in the FSM. It's a small diagram-I don't remember the page. I'll try to look it up when I get home. I used it to determine what thermister to buy to improvise with a head with no temp sender. Quote Link to comment Share on other sites More sharing options...

I did not see one for the dash gauge. They are separate sensors. Quote Link to comment Share on other sites More sharing options...
z-ya Posted November 14, 2011 Share Posted November 14, 2011 Why not just use the correct sender for the gauge in place of what is in the VG30? It may just screw into the thermostat housing without any issues. For my RB25 saw I just use the 240Z sender. I had to drill and tap the RB25 thermostat housing, but that's not a big deal to do. Also, it should be a linear relationship between temperature and resistance because a resistor is a linear device. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted November 14, 2011 Author Share Posted November 14, 2011 I'd have to drill it out and retap, but I will measure first. When I say curve, I mean y = 0x^2 + bx + C Quote Link to comment Share on other sites More sharing options...
