Suitable transient voltage suppression diode
Suitable transient voltage suppression diode
(OP)
I have a 1992 Dodge Stealth with a relay that no longer works, The circuit is fused for 15 amps and is 12 volts. After some investigation I have determined that a transient voltage suppression diode, which was soldered into the relay, is open. This very tiny diode has the number 77 on it and also has the number 1 then a dot followed by what appears to be the capital letter I (eye). Can a replacement diode suitable for this circuit be recommended? Any help is appreciated

Did you confirm the price of a new relay. Some common types are not very expensive, under $3 shipped.

But it can, and does, cause the relay drover Circuit to fail. If it is Electronic (a transistor for example) it will be hurt by the inductive overvoltage that the diode is supposed to handle.
You may need to look a bit further. Finding and replacing the diode is OK, but there could be more to look for.

Half full - Half empty? I don't mind. It's what in it that counts.

Ouch! Good luck with the diode repair.

Do you have a schematic drawing of the relay along with the test procedure in PDF form?

Any time you connect probes across a closed contact you will see voltage drop, 0V is good.
Black test probe to neg. supply and red probe to either pin 8or10 to read source voltage maybe.
