Hey All
I have a circuit connected to my Kit Car but I have found that a transistor keeps blowing and I'm not sure why. I know the environment of a vehicle isn't the best but I am running a Motor Bike Engine with a 1.4 Car Battery. I have monitored the battery thinking I was getting large voltage spikes but it very stable. My battery voltage goes from 12 - 15v when being charged by the alternater.
SW10 is a mechanical switch which is switched, this allows RL1 to switch. Sw4 is a PIC Pin Drive to Hold the relay enabled, regarless of the SW10.
Can anyone give me any advise on how I can protect this cct more?
Thanks.
