green_380 Posted Saturday at 05:13 PM Share Posted Saturday at 05:13 PM '84 R model showing all red lights except aux when circuit chaser is plugged in. Any idea what could be causing red lights. When a circuit is chosen it turns to green except turn signals that when activated green and red light fluctuates on blinker. Thank you in advance.
