Response to oilyspill in reference to 1998 dodge ram 2500
Thanks for your suggestions. I test all fuses, made sure starter relay was good
and checked fuses. still no crank. went to starter, B-post had 12.47 volts, had
helper turn ignition test trigger post and had around .5. Figure solenoid or
starter bad so I replaced starter. Still no crank! Ugh. Possibly bad neutral safety
switch or linkage adjustment?
Did you try jumper cables or jump box to see if starter motor would crank? If your getting .5 volts at ignition feed to starter, key in crank position, that isn't right. If you pull relay and use jumper wire between terminals 30 and 87, the starter motor should crank the engine. Just make sure transmission is in park or neutral and parking brake is set. Vehicle can't move. If it cranks, problem on control side of relay, terminals 85 and 86 in diagram. The control side needs voltage and ground. If you use test light between those two terminals and have helper turn key to crank, if the lamp comes on, there is voltage and ground, good enough for the lamp. If lamp comes on, nothing wrong with neutral switch.
