I'm making true voltage protection boards for automotive.
(1) MR 2535 Motorola avalanche rectifier
(3) 16 volt Transient Voltage Protection diodes (600 watt)
(2) 17 volt Metal Oxide Varistors 40 joules
(1) 470uf 35 volt electrolytic capacitor
Housed in a small project plastic box.
Each device except for the electrolytic and MR2535 is protected with an individual 2.5 ampere fast blow "rice grain" fuse.
And my oscilloscope is 2,500 miles distant...
The device is going to be connected to IGNITION B, which is on when the key is on 100% duty cycle.
This will utterly kill A/C compressor clutch and starter motor voltage spikes of greater than 16 volts amplitude.
