Title: fan monitor light thought
Post by: Lucky on August 15, 2007, 10:18:22 AM
I'm installing a fan monitor light (12v bulb tapped into the fan plug)

I'm thinking it'd be more noticeable if it flashed, so i thought, use a generic 12v turn signal module.  I'm also thinking i might have to throw in a resistor to make it flash faster than it would by itself with that one tiny bulb.

think a diode would be needed to keep the bulb from completing the curcit?

any thoughts?

Hmmmmm..
That gives me an idea of what to do with one of the two extra lights on my new digital gauges.  Or, now that I don't need the "idiot lights, I can rewire it for other indicators.  The possibilities are endless.  ;D

Lucky,
          An electronic or motor driven 'Heavy Duty' 2 wire unit will flash OK. You only need the load of multiple lights when the flasher is a bimetal spring switch. They need the current to heat the flasher switch bar enough to bend and 'click'

Heavy-duty flashers will flash slower with only one bulb on it. Use a standard flasher and no resistor is needed - this will only dim your light and decrease your flash time. If you want it to flash faster, use an LED (w/ a 820ohm 1/4w resistor inline) instead of a standard bulb.

You could use a 10mm jumbo LED super bright LED and use a 560ohm 1/4w. This would be so low of load on your flasher that the flasher might flash too fast.

Just my 4¢.

Stupid simple little job kicked my @ss, so i didn't post results last night.

put the bulb in, wired one side to ground, the other to the blue wire at the connector, works like a charm, & is bright enough.

problem came when i went to replace the shortie stalk that kevin sent me to replace the one i broke when i dropped the bike this spring (i had super glued it back together for a quick fix).  after everything was back together i couldn't get the turn signals to flash.  i had also taken all my connectors apart & sprayed them with CRC, so i thought i misconnected something, then i went thru the tests for the flasher relay, etc & still couldn't get it. 2 hours later i was still at it!

turns out that i had the t/s wires hooked up wrong.  since i've converted them to 1157 bulbs, i had 6 wires to deal with & had my grounds mixed up.. DOH!!

anyway, while i was trying to get them working i had the bike running in the car port, & in the 98 degree heat, the fan came on. i wouldn't have noticed it but the light came on, lol!

btw, the bulb i used is Radio Shack # 272-1141, & i modified a panel bulb (just used the socket) from Ace hardware: http://www.acehardware.com/product/index.jsp?productId=1286386&cp=2568454.2632232.2632332.1259239&pg=2&parentPage=family

and used a black paint marger on the white part to blend in with the dash

Thats the exact same one I was looking for in my workshop for you the other day. ;D

Radio Shack sells all kinds of LED lights, all sorts of colors, including ones that flash all by them little selves. I bought one today (Non-Flashing) for $1.99

I used the high-beam light.

Here is a secondary "Fan Monitor Light Thought"....

I am thinking of putting one of those CPU Computer Fans on my R/R and having the fan for the R/R come on when the Radiator Fan come on all with the indicator light on the dash. Whadayathink?

my R/R gets hot way before the rad fan ever kicks on...  cooler airstream gets my vote.

kevin makes these dandy mounting brackets for them.

As one of the CPU fan users, I have mine come on with the license plate light.  On whenever the key is on.  Those fans use so little power that the V's battery would run it alone for many hours.  If you leave your key on, the lights will kill the battery much faster than the CPU fan will.  One of my pre-ride checks is to listen for the faint whirr of the fan.  While it's a neat idea, I'm a firm believer in keeping things (especially wiring) as simple as possible.

So far, I just watch my temp gauge. Fan monitor light will go in later. Just for something else to look at. I do have an ammeter and voltmeter on order and thinking on a custom pod for them. They won't get here for about two weeks. We will see.
