An update on this TireMinder TM66,
I did not have any takers on this unit for parts so I dumped the programming and completely reprogrammed it. I ran it on my car for several days and it now works perfect. I have it back in the original box with accessories and I also marked each of 4 sending units with correct programming for each of 4 tires. (LF, RF, LR AND RR) All you would have to do is screw the sending units on. I set the tire pressure at 32psi for my car so if you will be using it on your RV tell me your pressure threshold and I will change it prior to shipping.
$75 and you pay shipping. Let's assume shipping will be $10 or less so send me $85 and if shipping is less than $10 I will put the difference in the box prior to sending it.
PS, I think part of the original problem with this unit was a couple of bad sensors. There are now only 4 good working sensors. I threw the 2 bad ones away along with a few choice words.........
I forgot the pictures.
