The problem is that there is a short circuit or any accessory is consuming energy that you can try a test lamp will turn the power tongs place the lamp in the positive cable must be disconnected and the tip of the lamp at the terminal the battery if the light intensity lamp is lit with a power consumption because if this happens remove fuse fuse when you turn the call light is the circuit that is causing you problems. Thanks

In a word no, you do not have to drop the exhaust to remove the starter.

Take a small 90 degree pick. Inspect the fitting closely. Use the pick to "roll" the retaining clip off the fitting. The line will simply pull once this is done. U can install the clip first on reinstallation (inspect them closely) and then simply push the line into the fitting. It will "click" into place. Note u will have to orient the line perfectly to push in.

You need to check the power to the aux power unit. If it has power to it then you know the unit itself is bad.

When you tap into the purple wire does the Trax II gage work or not?
