My keys cov 1 treadmill starts up, then speeds up and shuts down

I hae a Pro Form 540 Iteracive Trainer treadmill.
When the key is inserted, the treadmill cuts on but the control panel doesn’t seem to work when you touch start. I waited and cut it off and went back later and it did start but when I tried to increase speed, the speed button didn’t work. Then when I hit “stop” on the panel it did not do that either. I had to take the key out to make it stop.

Belt just runs at max speed automatically 🙁

3 year old Toro Z4200 time cutter Z, 19 HP Kohler, engine runs great, new battery, new solenoid, with the seat sensor connected or by-passed, STILL WONT start off the key switch. Clicks at the kill relay. Would the kill relay be the problem?
Whats confusing is, both the green and blue posts on the solenoid have 14.01 volts when you turn the key to ‘start’ position. Did the same thing with the old solenoid, which is probably still good. I replaced it to eliminate that variable. It also ‘clicks’ at the fuel switch at the carburetor bowl, but that is only 1 lead (I assume a hot lead) so Im thinking that CANT be it.
Using the old hillybilly method, jumping across the 2 top posts on the solenoid, with the key in on position, it will start right up, run, drive and mow just fine.
So my best guess is this ‘KILL RELAY’ must be bad?
Any help would be appreciated, thank you !

The Bike Technicians Tactic Phase1 An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician’s tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities. Engine Technicians Tactic PHASE 2 A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.

I have a New Balance 1400 (a few years old). When I run (7.0 or higher) the treadmill shut off. I loosen the belt than I retighten it. I ran 5.5 miles (ranging from 7.0 to 7.4). It ran great. Today it shut off before I got to 1 mile, Than I got it running again and it shut off after only .5 miles.

I was using my DK City treadmill and suddenly it stopped and flashed E7 and now as soon as you press the start button it starts flashing E7 and won’t start up. What is wrong with my treadmill and how do I fix it?
