TPS help....yet again

[mikeboileau]

That info would be good to try to restore.  The ECM flashing info too.

I think I'm going to do this at the next tire change. The front will be first. Where did the batteries with the tabs come from? Its really sad we lost all of this stuff. Seems like nothing on the interwebs is ever truly lost or can be really erased once it is there. Do we have any guru's who would know if this is true? Google scans and caches everything it seems.

That battery would probably work but it would require short jumpers to reach from the original sensor arms to the battery tabs. The original battery tabs are offset quite a bit from directly horizontal.

Someone mentioned having custom battery tabs welded onto the correct battery for just a couple of dollars at a battery supply company (maybe it was Batteries Plus ?). That would be an ideal solution of course.

I cannot remember the user name here who successfully used these batteries and who posted this source. He said that he was able to bend the tabs to reach the sensor arms. When I opened my TPS I saw that there WERE "jumpers" running from each arm to each tab. I intended to ask the poster wether he reused these jumpers.

[B.D.F.]

In the original link you posted, the tabs on the batteries were facing 180 degrees apart- that is the battery I was commenting about. Using that specific battery, the arms in the original TPS sensor are not long enough to reach the tabs.

In the pictures you posted in the more recent post, the tabs exit the battery more like 90 degrees apart and I am sure those batteries could be made to work with the arms already in the TPS sensors.

Sorry to mislead, I was in too big a hurry when posted. I failed to explain that the picture you are referring to shows my attempt to bend one tab in into a reachable position. The actual unmodified battery has two tabs 180 degrees apart. I still think a short piece of wire might be necessary to reach, or perhaps a better bending job than I did,

More pics should expalin better than my words, original and other side of modified battery:

Gotcha- that was like a 'slight of camera'.    It looks like it would work although you might have to shorten the original tab as it sticks out pretty far.

It probably won't make any difference but the bend in the tab might be subject to fracture due to long exposure to vibration. Really I don't think that would happen though as the battery is pretty well captured and really won't allow the tabs to vibrate anyway.

This would be a good service for someone to provide.......

[jonathan]

I thought that Murph was working on that?

[TPXX]

Has anyone used Murph for this? Has Murph made it over from the old board?

[B.D.F.]

He did post prices for the service on the old forum so I assume he is still doing the battery replacement.

This battery may also fit. I am not sure if the tabs are too close together.

It may have been the thread I posted a couple of months ago about replacing the TPS batteries.

This is a really easy project, so don’t be intimidated; some attention to detail and basic soldering know-how are all you need.

Here’s the battery info from my order:

Ordered: 2 Shipped: 2 CR2032-T4-2 Sanyo CR2032 3 Volt Lithium Coin Battery W/2 Hole Mounting # CR2032-T4-2 $2.50


Purchased from: BatteriesAndButter.Com Tel: (718) 491-2702 Fax: (718) 491-2707


Seem to recall that the two of them cost ~$15.00 to my door and most of that was shipping.

These batteries work just fine, but you do have to slightly fold the tabs to get them to fit.

First suggest you mark each TPS as “front” or “rear” so you know where to re-install them.

As Lather said, peel back the label on the back of the unit and use a tiny torx drive to remove the back. Be careful, as the plastic is easy to break. You can coax it off with a small flat-bladed screwdriver, just don’t force it.

Once the back is off, the battery and guts of the sensor will pull free from the plastic housing. Suggest you use a heat sink to keep from over-heating the electronics; somebody found a $2.99 Radio Shack heat sink that would work fine.

I used de-soldering braid, and someone else liked a solder sucker, but either will work to wick up the old solder. Once the soldered joints are free, the battery will fall off. You should note the polarity of the old battery’s connections, “+” or “-“ and place the new battery in likewise.

Fold the tabs to meet the TPS’ connections, re-solder, put the guts back in the case, snap the top back on the sensor, replace the torx, smooth the label back on and it’s finished.

The sensors have a rounded end and a squared-off end. Kawasaki does not spec which direction relative to the wheels’ rotation to place these, but Fred found that the ‘Wings say to place the square end toward the wheels’ travel. I didn’t pay attention to how mine were installed, but replaced them square side toward the breeze.

My TPS has worked perfectly for ~3000 since I replaced them. It was much easier for me to go this route than to screw around with a dealer.

There was early speculation that you had to jumper the units to keep them hot while the battery was removed, or that the tires had to be inflated to wake up the sensors. I did neither and mine are perfect.

Hope this helps!

Mike
