T16 restoration starts in earnest

hi Guys, thanks for the comments Rod, not sure why but I didnt get a notice that there had been a reply on the thread so hence I didnt get back to you. I managed today to pick up 2 NOS water pumps for T16, so I think I will be ok with these now. What is taxing me, however, is the blessed wiring!!! My gauges have minds of their own. I know I am wired correctly, but the temp gauge jumps full right when you connect up the senders, and the oil pressure just jumps around and does what it likes. They are fed through some resistor type item called a voltage divider, which I have no idea what it does! Any help much appreciated. Also, may need a NOS solonoid, as it only works if I tap it. It may clean itself off inside, but they dont appear to be a serviceable item, so cannot get inside easily to take a look. Grrr, I want to go for a run in my baby but cannot until I can get this wiring sorted!.

ps, Rod, sent you an e mail a few days back , maybe you didn't see it?

Andrew,
I think I have starter solenoids for the T-16. Sounds like you may have a ground problem with the gauges. I think the gauges are 6 volt gauges, so, the voltage has to be cut down for them to work properly, hence the voltage divider as you call it. I will check on the solenoid and get back with you- Rod

thanks Rod, if you could that would be great as its knackering my knees having to turn the ignition on in the front and climb into the back to manually press the solonoid. Too old for this. Please check if you have any NOS instruments for T16 as well, cheers

on the gauges being 6v this is where it gets complicated! I have been told that they are 12v gauges but not many US gauges were marked with which voltage they were, hence the confusion. The TM refers to all electrical equipment being 12v EXCEPT the ignition, which rather points to the instruments being 12v. I have also been told, since my earlier post the voltage divider that is wired in line with the instruments power supply is in fact designed to stop the gauges going up and down with the variation of the charging system. Sounds credible, however, if thats the case , why do Jeeps, Dodges etc not have them? Maybe they do?

Hi Andrew,

I am sure the description of the resistance unit, on the wiring diagram says it all, a volt divider, bringing down the 12v sytem to presumably 6v for the guages, although when I checked the output with you, it was 9v, this may be because the resistor has suffered inside. I have looked around and cannot find any information to confirm the Volt Divider output.

regards, Richard

Andrew,
I have NOS Fuel gauges, oil press. gauges and temperature gauges, all for the T-16. They are $45 ea. I put new ones in my T-16 and they work great. I don't have any amp gauges right now. Rod
