jt79zxt Posted July 14, 2010 Share Posted July 14, 2010 so this is wired to a (key on) 12 volt source...my question is once the 12 volt goes through the resistor what should be the voltage ? or should there be any ? might seem like a stupid question.. just trying to figure my install problem..

jacob80 Posted July 14, 2010 Share Posted July 14, 2010 I'm sure you mean 1/4 WATT 1k ohm resistor. What seems to be the problem? Quote Link to comment Share on other sites More sharing options...
jt79zxt Posted July 15, 2010 Author Share Posted July 15, 2010 your right... I have power before the resistor (tested with test light) but afterwards there is nothing.. just wondering if this is nornmal... Quote Link to comment Share on other sites More sharing options...
Zmanco Posted July 15, 2010 Share Posted July 15, 2010 your right... I have power before the resistor (tested with test light) but afterwards there is nothing.. just wondering if this is nornmal... Yes, this is normal. The 1k ohm resistor will limit the current enough that a typical test light will not light up. If you are trying to measure continuity through a resistor, then you need a digital voltmeter (DVM). You can get a decent all around version for about $25 at most auto parts stores, and an el cheapo at harbor freight for $2-5. Perhaps you should start over with what the problem is...

jacob80 Posted July 15, 2010 Share Posted July 15, 2010 Yes, please state what the problem is and we can go from there. Quote Link to comment Share on other sites More sharing options...
