[Stuck truck]

It's a motor home on a Chevy van chasy. It started last month and now it won't even turn over.the battery has 12v and the lights work but not the radio. I replaced the starter and tested the wires from the egnition to the starter and I have power. I've checked the fuses and traced the wires that I think should have power. I need help, my rig is dead I can't even get a click when I turn on the key.

Pay particular attention to Item 6. Static battery voltage should be at least 12.8 volts.

"Car (Starter Motor) Won't Crank"

. Ensure the battery is fully charged, even if it's a new battery, before diagnosing starter problems. Then, test each cell, with a hydrometer or multimeter, to ensure that it's good. This important step is often overlooked.
. Test all under hood and under dash fuses with a test light or multimeter.
. Ensure the gearshift is in Neutral or Park (automatic transmission), or the clutch pedal is depressed (manual transmission), if the starter motor does not turn at all when the ignition switch is turned to Start.


1. If the starter motor doesn't turn, but the starter solenoid (relay) "clicks" when the ignition switch is turned to Start, the problem is with the battery, starter solenoid, or starter motor connections.

2. Disconnecting the negative battery cable first, clean battery terminals and cable connections with a battery terminal brush, No. 240 abrasive cloth, or steel wool. Also, check the battery ground cable connection to the body and engine. Apply silicone dielectric grease, when finished. Examine the cables carefully for hidden corrosion or internal breaks.

3. While the negative battery cable is disconnected, clean starter motor and starter solenoid connections. Apply silicone dielectric grease, when finished. Make sure all connections are secure. When installing the starter cable, make sure that the crimped side of the ring terminal is facing out. Reconnect the negative battery terminal last.

4. If the starter motor spins but the engine is not cranking, the overrunning clutch in the starter motor is slipping and the starter motor must be replaced. Also, the ring gear on the flywheel or drive plate may be worn.

5. If the solenoid plunger cannot be heard when the switch is actuated, the battery is bad, the fusible link is burned (circuit is open), or the solenoid is defective.

6. In order to check the solenoid, perform an Ignition By-Pass Test, by placing the transmission in Park, engaging the parking brake, removing the push-on connector from the solenoid “S” terminal, and connecting a jumper lead (12 AWG), or preferably a remote starter switch, between the positive battery terminal (or B+ terminal on the solenoid) and the exposed “S” terminal on the solenoid. If the starter motor now operates, the solenoid is fine and the problem is with the starter relay, ignition switch, neutral safety switch or clutch interlock switch, fuse, fusible link, security system, or wiring. If the starter motor still does not operate, replace the solenoid.

7. If the starter motor cranks the engine slowly, ensure the battery is fully charged and all terminal connections are clean and tight. Then, check connections at the starter solenoid and battery ground. The engine will also crank slowly, if it's partially seized or has the wrong viscosity oil in it. Synthetic engine oil allows starter motors to turn the engine over easier and faster, thus promoting starting and reducing battery drain.
