This whole relay coil voltage discussion makes me wonder whether these
relays are really "12V" relays, and not 24V relays. True 12V relays
will typically pull in at 6 to 8V (they just take longer) and will
certainly pull in at 12V every time. OTOH, 24V relays will often
sort of work from a 12V supply, especially if it is really 13.8V.
24V relays are much more common and often available at reduced prices.
The relays could also be mismarked. I bought dozens of relays marked
"24V" that turned out to be 6V relays. The seller did not realize
this and said he got them surplus or on the gray market. The relays
were worth far more to me as 6V relays than 24V relays, so I was
happy.
Supposedly these relays are custom made. In that case, it should be
possible to wind the coil so it works on, say 10V, so that in any
nominally 12V system, it would always function.
