I'm trying to get to know my fuse and relay boxes better. They're labelled, but the labels are mostly acronyms and shorthand, and googling any particular acronym gives a lot of mentions of common tasks on forums but not any definitions or explanations (at least not that I can find).
I think it's probably easier to ask them all together and create a definitive go-to guide than have over a dozen questions which for an expert are absurdly easy with potentially one word answers. Maybe a great answer could help a novice like me understand how the different items interrelate. Note that StackExchange policy on "list questions" are that they're okay if they're clearly bounded and finite, like this, it's never-ending lists with an unlimited number of possibilities that are "too broad".
These are specific to my 1998 Toyota RAV4, but it'd be good to have a definitive universal resource, so please comment and/or feel free to include in answers any common ones for other makes that are missing.
Relays
- E/G Main
- H-LP
- ST (I suspect this controls the starter motor but could be wrong)
- EFI (95% sure this is "Engine Fuel Injection")
- MG/C
- DIM
Fuse acronyms are all detailed in the owner's guide, which for this model is available online, but relays are not detailed in the owner's guide at all.
