Re: Pressure transducer rebuild - note on one step Posted by JeffD [Email] (#1885) [Profile/Gallery] (more from JeffD) on Mon, 21 Dec 2015 22:59:56 In Reply to: Pressure transducer rebuild, TurboMarcus, Mon, 3 Aug 2015 15:26:36 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Thanks much for the instructions for rehabbing the transducer. I'd checked the one on my '92 mule, and found dead spots up above about 6 psi/~60 ohms.
I went through the exercise on two junkyard transducers for practise (one of which was just fine, oops) but misread this instruction and caused the transducers some grief:
"3. Heat the solder connectors at the end of the can to release the wires and internals from the outer can."
and ended up breaking one of the wires on the first transducer, then reaching inside the cut-open transducer on the 2nd with a small pair of scissors to get it apart, on the second.
The 'solder connections' on step #3 are the brass screw terminals with the spade connector adapters screwed to them. They are actually hollow and have a 1.5mm throughhole that the wires run through.
At first, I'd thought that the wires were crimped to the screw terminals internally, and somehow the terminals were press-fit into the plastic of their mount.
It wasn't until I looked closer that I saw the silver of the solder. I heated up the terminals with a soldering iron, pulled the wires out, used a solder sucker to clean out the holes, followed through on one of them with a ~.060" drill bit, and put new 24AWG wires in place.
