UAZ Patriot fuses - what they are needed for and what they are responsible for

The fuse is responsible for the proper operation of the electrical circuit and in the event of an overload or short circuit, the fuse of this part burns out. If one element burns out, the driver detects a malfunction of any electrical system of the car. Therefore, in order to eliminate the malfunction, you should first check the fuse link, which is located in a special block of the UAZ Patriot SUV. But in addition to these parts, the SUV also has relays, which also fit into the mounting device.

To visually imagine the location of these parts, below is a diagram with numbering, with the help of which we will consider the purpose of not only fuse links, but also relays.

So, this diagram allows you to consider in detail where each element is located and what it is responsible for. For ease of review, the information is presented in tabular form.

Where to look for a node

It should be noted that in order to find the main fuse block on the UAZ Patriot, you do not need to go under the hood . In a domestic SUV, the device is located inside the cabin, next to the driver’s left knee.

There you will see a cover behind which the element is located. Removing the cover is quite easy - you just need to turn the lock to the side.

There is also one more mounting block. It is located under the hood, on the left side of the mudguards. The lid here opens in the same way as in the interior unit.

Similarly, for starters, there is a diagram of the location of fuses in the engine compartment, which are responsible for the operation of such circuits.

The relay and fuse box under the hood is located on the left mudguard extension of the car. The layout of the relays and fuses is located on the inside of the unit cover

Depending on the vehicle configuration, some of the relay data may be missing, as shown in the diagram. This material allows you to quickly find out the purpose of the fuses of the mounting block, which is often necessary when one or another component on a UAZ Patriot SUV does not work. Therefore, now you can quickly and easily find the fault and fix it, the main thing is that you always have a set of spare fusible products for the mounting block in the glove compartment.

UAZ Patriot (2011). Starter relay malfunction

Basic relay malfunctions and how to eliminate them

The most common problem with a starter is that the mechanism refuses to work at all: it does not click and the armature does not rotate. The reasons for this behavior of the unit can be both electrical and mechanical factors.

Electrical

- no discharge from the battery. In this case, it is necessary to check the battery for defects: oxidation of contacts, destruction of plates or damage to the case. Depending on the severity, there are two options for salvation - recharging the battery and replacing it with a new one; the wires on the battery have oxidized. You just need to clean the contacts. To do this, use fine-grained sandpaper or a regular toothbrush. Cleaning the tips should be done very carefully so as not to damage the outer layer, - insufficient tension of the tips, - a break in the electrical circuit between the ignition switch and the starter. The damaged section of the circuit is being restored - a short circuit in the relay winding. Eliminated by rewinding or completely replacing it - the armature of the device gets stuck. It is necessary to install a new solenoid relay; there is a malfunction of the ignition switch contact element. This can only be solved by replacing it with a new spare part.

Mechanical

– the starter works, but the crankshaft does not rotate and the engine does not start, or there is extraneous noise and grinding noise in the operation of the starter mechanism.

- the slip clutch is broken, - the release lever is uncoupled from the axle, - the buffer spring is out of order, - the drive ring is worn, - the gear teeth are worn out, - the starter fastening screws are loose, - the pole retainer is loose.

First signs of concern:

-The starter does not start immediately, but after several test turns of the key. This indicates burning of the solenoid relay contacts. To eliminate the problem, you need to clean the contacts. -The starter mechanism rotates, but it is too slow, while the battery is fully charged. In this case, you need to pay attention to wear of the brushes or wear of the bearing device. -After the engine starts, the starter does not immediately turn off. This means wear on the gear teeth in the bendix or the flywheel ring.

Malfunctions that may occur with the solenoid relay are:

-Wear of its elements; - Burnout of contact plates installed in the housing cover; -Breakage or burnout of the relay coil winding; -Anchor jamming.

The occurrence of these malfunctions may result in:

- Failure of the starter to operate when starting; -Weak starter speeds, which are unable to sufficiently spin the flywheel; -Continuation of its operation even after starting the engine.

How to troubleshoot

Troubleshooting a traction relay is not that difficult. It should be noted that its operation is accompanied by a click - this is the result of the armature being retracted and the gear being engaged.

When you turn the key, this click is clearly audible. Thus, the absence of a click may indicate a break in the coils, lack of power, or the armature being stuck in one position.

-If, when you turn the ignition key, a click is heard, but the starter itself does not start or starts, but spins very slowly, this may indicate that the contact plates are burning. -Continuation of the starter operation after starting the power plant will be accompanied by a characteristic buzzing sound. -It is possible that the armature is stuck in the retracted position and cannot return back, so it keeps the bendix gear in mesh and continues to close the contact plates.

If the traction relay is activated, but the starter armature does not turn, then the reasons for this may lie in:

-The battery capacity of the battery is discharged only enough to operate the relay, but not to rotate the armature.

- Presence of scale on the armature commutator or its burning.

-Insufficient tightening of the wires with bolts on the starter traction relay, which in some cases can lead to sparking of the contacts.

-Breakage of the armature and stator windings.

-Short circuit in the collector between the plates.

-Short circuit of the positive contacts of the starter to ground, for example, the brush holder, or an interturn short circuit in the armature and stator, to each other or to ground.

-The presence of oxide on the wire contacts and battery terminals, which does not ensure stable current transmission to the starter.

- Worn brushes or their depressions in the sockets.

- Melting of the winding as a result of overheating of the starter and, as a result, its short circuit.

The relay does not operate and the armature does not rotate, reasons:

-Breakage of wires or short circuit of the pull-in or holding windings of the traction relay to each other and to ground;

-Sticking of the traction relay rod.

-Failure in the contact part of the relay.

If nothing happens when you start the engine:

-The fuse has blown. See the electrical diagram and replace the last one.

-The ignition switch is faulty.

-The starter relay has failed.

-See the above faults; short circuits can occur both in the relay and in the device itself.
