A 315bl excavator. Engine intermittently shut off on its own, but will start back up without a problem. Now machine will not shut off when key is off, happens every day now. I sometimes have to choke off air intake to shut down. most of the time the engine will restart then shut off. (1) Disconnect switch. (2) Batteries. (3) Power circuit.(4) Breaker 1. (5) Main relay. (6) Fuse box. (7) Low current circuit. (9) Cigar lighter.

(19) Starter motor. (20) Starter relay. (21) Alternator. (22) Horn. (23) Controller. (24) Switch panel. (25) Shut down solenoid. (26) Heater control unit. (27) Glow plug. (28) Charging circuit. (29) Timer relay. (30) Neutral start relay. (31) Battery breaker. (32) Breaker 2. (33) Breaker 3. (34) Fan relay. (35) Shut down timer. (36) Heater relay. This circuit supplies power to electric components and includes battery (2), disconnect switch (1), battery breaker (31), breaker 1 (4), breaker 2 (32), breaker 3 (33) and main relay (5). This circuit starts/stops the engine and includes starter control relay (10), starter motor (19), starter relay (20), timer relay (29), starter switch (11), shut down solenoid (25), neutral start relay (30), neutral start switch (12) and shut down timer (35). Some machines are equipped with starting aid for cold weather starting purposes. The start aid circuit consists of glow plug (27), heater control unit (26) and heater relay (36). This circuit distributes power to several low current components. By operating switch panel (24), this circuit puts on lights (15) installed at chassis, cab and boom. Also, this circuit controls continuous or intermittent operation of the windshield wiper (16). (2)...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
