hey all,
I'm gonna try and simplify my issue, I have a MICROCHIP Pic18f4680 controlling a relay using an optocoupler, the relay switches the negative side of my horn. The positive side is connected to a bus bar.
When the horn is switched I seem to have weird switching on my PIC, captures capturing and other signals doing weird and wonderful stuff, like it's doing something weird with the battery supply.
When I remove the horn and get the relay to switch with no load it's all good.
What could be going on, how can I stop it???
