Guys I'm trying to convert a suction cup mount 3v (2x AA) compass w 4 leds to a permanent 12v dash mount in an instrument pod.
I've soldered an lm1086ct 3.3 v regulator w 1.5uf caps from the in and out to ground on the regulator pins. Then soldered wiring to the in and out pins.
With 13.5 v in there's only 1.7 v at the output pin. Could I have killed the 1086 or caps by soldering them to the 1086 pins?
Next I traced the circuit board power and grounds, then carefully cut out the 2v parellel led circuit and powered it from 4 individual resistors. This to be powered from my van lighting circuit. Leds work okay.
It's very time consuming but a great project and if it works will be a unique option for my 4x4. Not my field of expertise but I've done worse.
I'll be reading "all about circuits" but needed a helping hand on this project. Great site, gives confidence.
Thanks for the help.
