summit gauge questions

i had a set of those on my scout while i was doing break in . the oil pressure worked fine (still works now) but the volt meter did not work and i found out while doing the break in that the temp wasnt working either. this was about 8 yrs ago, i think they are equus guages.. if i want cheapo guages i use sunpro, but for all my good stuff it gets the autometers (mainly because they look better, i dont think they are any better in quality imo).
also every mech oil guage i use gets the autometer braided hose kit, it never leaks.
