Main Switch
- If fuse is okay, check for continuity between terminal No. 3 (terminal No. 20 on MR2 and terminal No. 1 on Van) of main switch and body ground. See Figure. If continuity is not present, check for open between terminal and fuse.
- If fuse is blown, replace fuse and recheck. If fuse blows again, check for short between fuse and switch. Check switch operation. If continuity is present, check for battery voltage between terminal No. 2 (terminal No. 16 on MR2) of switch and body ground.
- If battery voltage is not present, check for open between terminal and fuse. If voltage is present, check for battery voltage between terminal No. 6 (terminal No. 21 on MR2) of harness side of connector and body ground with main switch turned on.
- If battery voltage is not present, inspect main switch. If battery voltage is present, inspect indicator light operation. Connect terminal No. 4 (terminal No. 18 on MR2) to body ground. Indicator light should glow with main switch turned on.
- If indicator light does not glow, inspect main (control on MR2) switch. If indicator light does glow, check to see if light glows with main (control) switch turned off.
