Possible solution to frequent sensor replacement
I frequently leave my bike parked for weeks or months at a time, so couldnâ€™t see any reason Iâ€™d want to have sensors transmitting 24/7/365. So when I installed my Doran TPM I did an external sensor placement (with steel valve stems), and wired a hidden, but easily accessible rocker switch in the 12V power lead to the Doran monitor.
When itâ€™s time to park the bike for a while, I just turn off the monitor with the rocker switch and remove the sensors from the wheels; Iâ€™m pretty sure that the sensors stop broadcasting after some fairly short period of time. Yes, the batteries will still wear down eventually just because all batteries do, but they should last a lot longer than if theyâ€™re sending out a signal every few minutes day in and day out.
The test: after the sensors have been off the bike for an hour or so, and the monitor off, flip on the rocker to supply power to the Doran monitor. The monitor waits and waits, but nothing ever shows up, because evidently the sensors are not transmitting. With the monitor still on, reinstall the sensors, and bingo, they immediately show up on the monitor.
Anything wrong with this logic?
Iâ€™m giving 4 stars, even though the system works great, because I think the monitor is a real eyesore. Itâ€™s just a box, ~2â€ x 1 â…â€ x 1 â…œâ€, and sticks out like a sore thumb. I try to have my various â€˜farklesâ€™ look like they came with the bike, not just a bunch of crap and junk stacked all over the place. I think it would be a great improvement to shrink the monitor box down to something about the size of a small matchbox; much easier to integrate into an existing dashboard. I do realize, however, that most people could care less, and will be quite happy having the monitor box sticking up off their handlebars.
I do appreciate that one option is to hide the monitor box somewhere, and just use the included alarm light (a nice touch), but I like to be able to just push a button at any time to check pressures.
