Customer Question

My husband has a 1972 jeep cj5 with a 401 javelin engine. Had no problems until now. He has replaced the alternator, seloinoid, starter, pretty much everything. Just bought an optima battery but something started draining the battery about 2 weeks out. Replaced the ignition switch and now there's nothing, no clicking or anything. Any ideas?

Be sure Battery is completely charged

Check Battery Cables Ground - & Positive+
Be sure ALL connections are clean & tight
Need to test the Ignition Switch Battery + input
Is there Voltage + to the Ignition Switch?
From the Ignition Switch:
Key held in crank position
Is there Voltage + to the Starter Solenoid?
Does the Starter Solenoid engage the Starter to crank?
let me know what you find so we can continue

He has checked the battery and all but not the voltage. He doesn't have a voltage meter but if we were to buy one does it matter which kind or does it need to be a certain voltage reading or anything along that line?
Expert:  Don 'Mo Lurch' replied 9 months ago.

Test Light will work also.........
Meter needs to read "DC Voltage" up to 20 volts or more

Everything has power. Voltage regulator, battery, starter, except the ignition. Everything is good.

You need to trace the Ignition Switch "hot wire" (the wire that comes from the Battery or Fuse Panel to the Ignition Switch for Voltage +
IF you cannot trace the wire, because it goes into a loom, run a temporary Fused (20amp) wire from Battery + to the Ignition Switch.
The Ignition Switch wire comes from the Battery + OR the Starter Solenoid & goes thru the Firewall, so you either have a blown fuse, loose connection or the Solenoid is wired wrong
