Every so often I have to read an automotive wiring diagram when trying to diagnose some problem, whether for myself or for friends. I frequently either forget what a DC electrical symbol or identifying letters mean, or run across some I haven't seen before.
Is there a resource for identifying 12 volt wiring diagram/schematic symbols? I've looked online with limited results, and a lot of the symbols I wonder about are frustratingly not listed in the guides I've seen.
Two that have me stumped in my current effort are:
(1) the characters "TB2-11" next to a device on a wire between a relay and a solenoid, and the device is drawn to resemble a single bullseye - it looks like the two bullseyes inside the diagram's rectangular symbol for Circuit Breaker (CB); and
(2) the letter "S" with various numbers, such as "S1" or "S9", etc., drawn either in a single wire run or at the juncture of two or perhaps many wires - is that a Sensor or just some sort of junction block Stud or something?
Thanks for any assistance.
