No Crank or power to dash
I parked 1991 Tiffen in driveway after coming back from Viginia. Tried starting next day. No luck . Battery has 12.5 volts, new starter, battery isolators, ignition switch (electrical part), Ignition control modual. Tried jumping starter relay, no luck. No power to relay. Hooked up aux. ground from chassis to engine block. Disconnected house battery no good. Haven't found any fuse in line. Any ideas ??? Or a link to 91 wiring diagram ? This is on a F53 chassis with a 460 CID. Thank you in advance.
