Rotary variable resistor 5% vs. 10%?
* * * Please note: I meant variable resistor, not pot * * *
I recently purchased a used Snap On brand timing light with advance. This feature allows you to pre-set the desired ignition timing degrees. Well when I went to use it, it would not work (read "flash") Long story short, I found the variable resistor for the advance would only allow the light to flash if you wiggled it.
I removed the variable resistor, it is a Bourns 3852C-252-502H. I have searched online for this with no success. I did however, locate a datasheet that deciphered the part number. The -502 refers to "5k" and the H is for ±5%. I was able to find 3852C-282-502A. The A means ±10% Otherwise, all else is the same. My question is, if I use a 5k resistor with ±10% accuracy over the original ±5%, will this cause a huge discrepancy in ignition timing degrees? Please help, oh wise men! (and wise women)
