help with electronics?
ok, im not too up on the finer details of circuit boards... a couple general questions. i need to replace a resistor on a home made box(not my design) i have lots of room on it. i dont have the proper resistor, but i have a bunch!  i can put 2 (or more?) in series to get the proper resistance correct? next big thing is im not exactly sure what i have. i bought a 40 pack, they arent labled, just colour coded. i googled but i want to double check i have the right ones. the target resistance is 24k ohms, but slightly lower is ok(just means not quite as much fuel is added, so that will limit the nitrous jetting slightly). listed on the back of the package, it shows that i have two of the following: 10, 22, 47, 100, 220, 330, 470, 1k, 2.2k, 3.3k, 4.7k, 10k, 22k, 33k, 47k, 100k, 220k, 330k, 470k, 1m
what colours do i need? thanks!

I really reserve the right to be wrong here!
Brown yellow red Red would be best
but I bet gold is more common or silver

Red - Yellow - Orange = 24k
Red - Red - Orange = 22k
Gold and silver tolerance bands are common at Radio Shack.

yes you can series a resistors for the desired resistance.

Or parallel them if you want to do the 1/r thing and drop the resistance.

An ohm meter (found in multimeter which mesures voltage and current also) can give you resistance values by measuring them....if that helps...
multimeter is a cheap item to get...comes in handy for AC and DC- voltage current and resistance values...and checking for continuity too!!....

I think it's the one on the backside of the board. It looks like Yellow-Violet-Brown (470) to me, and it's soldered into the relay with the capacitor.
Seems like a lot of complexity just to toggle in some extra resistance. I'd probably do it differently, but then again, my electrical skills are about as sharp as a bowling ball.

i dunno. looks more like a bleeder resistor..
scott, if you don't mind, explain to me in that thread what you're trying to accomplish..
unless it's buried in ther to read.
i just wanted a condensed version.

dads bike has some "old school" electronics, and i put on a dry nitrous setup. im basically making a map switch feature like you can get for the newer PCusb. he has the old PC3R. when the nitrous is turned on, the little resistor box tricks the ecu into thinking the bike is really cold, and richens the fuel by about 20% if you are at normal operating temps.
no messing around with loading the "nitrous map" into the pc to do a N2O pass, then turn around to take it back out to run NA. i want to make this very user friendly as dad isnt so great with computers, and im busy enough at the track with my bike.

the cap was to prevent the ecu from knowing the circuit was switched. no matter how fast you switch it, the ecu sees it unless you use a cap to give it a little voltage untill the connection is switched. if the ecu knows it was switched i believe it goes into limp mode. the cap prevents it

he decided to finish the rest of the season NA so i didnt hook it up. hes still getting used to driving it, and we are just focused on making the most of this setup before we add power. its been probly 20 yrs since dad owned a bike. its fast enough as is... for now
