This may sound weird, but I am looking for something that will delay a 12 volt power feed by 2 to 15 seconds (think a delayed relay).
The oil temp sensor went in this weekend, and so did the gauge, but the gauge has a wiring trick to it that is annoying me... Goes like this:
Gauge has four wires: power +, power -, temp sensor lead and light sense.
If the power to the gauge is hot, gauge is on. Thus, to have the power to the gauge shut down with the bike, the positive is tied to a switched source (in this case one of the leads for the unused California fan plug).
If the light sense to the gauge is hot when the power goes hot, it trips the gauge into a special setting mode used to set the emergency temp flash mode (i.e. - what temp to start flashing at me at instead of simply reading out the actual temp). On the other hand, if the light sense is delayed by 1 second or more, it actually acts as a dimmer for the display and the gauge never goes into the settings mode.
Since the lights on the pre '05 Kats turns on with the key (at the same time as the power from any switched power source), the gauge immediately goes into the setting mode.
So my choices are:
(A) to leave the display on super bright and keep the light sense mode wire disconnected, OR
(B) it put a physical switch inline (not desirable in my mind) to trip the light sense; OR
(C) attach the light sense to the low-beam feed (so it doesn't trip on high-beam, which I ride on during the day, but if I start with the lights in low-beam mode it would go into settings mode; again, not desirable), OR
(D) to find something that will delay the power to the light sense wire by a couple seconds (best solution).
Thus, here is today's quest: does anyone know of a standard item that I can put inline to the light sense wire which will delay the power to it by a couple of seconds? Surely there has to be something on the market that will do this...
