there is a ladder test in the electrical service manual that will walk you though the diagnosis.
Its based on what works and what doesn't.
So what works?
Mil lamp, battery lamp, security lamp?
Thanks Thermodyne, At least we're now going in a useful directiopn. Since I don't have the electrical service manual, mind walking me thru this?
What works- Everything EXCEPT anything on either the speedometer or the Tachometer.
Both gagues and their attached functions are completely inop, no lights, no needles, nothing.
All other gagues work, the oiul pressure , air temp, fuel, and ammeter all have back lighting and the needles function.
Neither blinker works, but the running light rings illuminate. What I mean is The CD fire rings are LED assemblies that have a row of White led's on the outer ring and amber rows on the inside . The outer row serves as a running light and the inner rows as the blinker. The running light functions but the blinkers do not, the flashers do not.
I can hear the fuel pump prime when I turn on the ignition but the starter does not work
What does work - everything else!
The headlights work on both high and low beam
The horn works,
the speaker switch, acc switch, and cruise switch all light up leading me to think they also work.
the brake light works
the radio works across all bands and voulmes
