0) I have a remote start unit from Bulldog Security model RS 82i rev 3d.0.0 It is 5-10 years old and I am hoping I can fix it instead of buying another one for $70.
1) When I hook up the wires as indicated I get power out through the ground. I know that at least one zener diode is bad but I'm not sure if I should just replace it or if it is likely to be something else. There aren't any part numbers on the diodes on the board but I was able to find some at radio shack that are similar in size. Is there a way test other diodes on the board to find out the necessary specs?
2) If I hook it up to power and ground I get a burning smell and I'm guess that is coming from the bad zener diode.
3) I'm attaching the manual if it will be of any use.
4) I have circled the burnt diode in the second picture. If I test the resistance it is 0 both ways. If I test the other ones on the board they all overload my meter.
Basically, I would like to know where I can get the proper diode or do I just take my chances with what I got (IN4742A)
Also do I need to remove the component c0322 (large black piece next to the diode) to replace the diode or just try to replace it how it is?
Any other thoughts/advice would be greatly appreciated.
