Der Sir;
The power switch is failure , you must Change the switch. You must be shure the some wires is Not loose, otherwise the wires will be touching the carcase causing the spark inside. Retight the wires or solder .You must inspect the main motor board and all the element around . If someone is burned or other wires is touching the carcasing producing the spaprk.
sincerely. God bless you.

Precor 905e turns off after i run at 10 mph for about a minute

When a running belt has excessive wear, it creates a lot of friction which causes the drive motor to work harder. When the drive motor works harder it will start overheating. If the belt is not lubricated periodically, it will ruin the deck, the drive motor, and cause other electrical problems such as tripping the breaker [after a while, the circuit breaker on the treadmill will need to be replaced.
It is suggested to lubricate the belt every month. At this point, you may need to replace both your deck and your running belt.
The following link will take you to our tech support page that contains some tips and videos on how to maintain your treadmill:

How long have you let it run for after turning it back on ? Some treadmills have a re calibration test built in and will incline to the max and work its way down. During this time you should simply walk away and not touch anything as it trys to calibrate its self. If not i will need more information on it

Is it on an extension cord? Take it off any extension cords and make sure it's on a dedicated 120v circuit. No other items on the circuit. Also, how old is it? Precor made a bunch of the 9.3x series from 2002-2005 with an aluminum tail roller that can cause problems. Check the back roller. Is is silver and non-magnetic? if that's the case, you have an aluminum roller and you need to contact precor. If you're the original owner of the machine, they should warranty the replacement of the parts, if not, you'll have to buy at the very least a running belt and new roller.

On switch flicks off when electricity turned on

The switch is also a circuit breaker it tells me that their is a good chance your Motor Control Board is shorted and will need to replaced or can be rebuilt. Call National Gym Supply @ 800-496-7278 and ask for pricing for new or repair.

Precor 9.25i treadmill running backwards.

The power leads Black/red will determine the direction that the motor will turn. If the leads have been switched to the wrong terminals at the lower PCA it will run backwards even if the black and red line up when the motor is plugged in. Check to see if the power cable on the lower board is in the right configuration. I've seen the terminals get switched when a new lower board is installed.
