I just installed a used wheat lamp its really bright. I didn't use the other white wire for ground but soldered the ground end to an existing can on the board. but 2 days later, poof, Not working. Im thinking if I should add a resistor inline. I tried one time adding resistor inline for 12vlt applications and it heated up.

Help!!!!

Not sure about the 2510; but I know that Cobra/Uniden radios go through a resistor so that it tones down the bulb strength. In fact, I did what you did awhile back and put the bulb getting direct 13.8v into a Cobra meter. Melted that meter within two days and had to replace it!
lol!
Live and learn.

I would go back into the radio and find out where the "+" wire for the original bulb was soldered - and attach it there.
Before you melt the meter like I did . . .

I dont think its the heat that killed it, I think the extra voltage is the prob. Even if I install an LED, Id still need a resistor in line thou.

Thanx for the info guys.
 
OK, thanx guys. Will keep ya posted. Looked so good to see the meter lit up, then this morning, kaput!!! :lol:

Will look around. Aloha james.

    Coax question. I just put up a new Sirio monsoon base antenna with 100’ of rg8u coax testing with myMFJ antenna analyzer shows 1.4 swr at 26.965mhz and a 1.1 at 27.405 mhz . When I checked the ohms it’s steady a 30 ohms across the entire bandwidth.
  • @ Geoexplorer69:
    Is 30 ohms worth worrying about in a 100’ run of rg8u ?
