hi I have a 1998 formula deluxe 583 and the electron ic fuel gauge is not working and the temperature gauge is not working, the previous owner replaced the regulator b/c of blowing headlights and I am wondering if mabey a fuse may have neeb blown for either of the gauges, if so where might i find where the fuses would be located for these, if it is not the fuses what else could it be, thanks for any help.
