Because of my skills, sometimes I have to repair electrical equipment and wiring in the cars of neighbors and acquaintances. As a rule, these are not Kruzaki or Cayenne, or supercars not stuffed with electronics.
These are ordinary, working machines. Both Russian and bourgeois. And the tractor and even motorcycles. Ignition locks are usually directly connected, half of the bulbs do not light up, instead of fuses there are usually pieces of wire, paper clips, coins, cloves - anything you want to keep current flowing. In many cases, the wiring in many places is fused and all on the "snot". What to do, the services of a good auto electrician are not cheap, so they do it, whoever is much worth it.
But the fact that the car burns down to an average of 5 to 8 minutes, none of the owners think about. Personally, I have twice seen how quickly this happens.
Therefore, I strongly recommend to all my friends and strangers car owners to install a switch "mass". First of all, for fire safety purposes, but also as an additional anti-theft tool, it will also not hurt.
To quickly install a reliable mass switch, you will need:
1. Thick copper wire with terminals
2. Automatic from 63A to 100A
3. Electrical tape
In stores, mass switches are still found in some places, but there are few really good and high-quality ones, mostly these are cheap Chinese crafts from plastic, which will inevitably melt during the passage of a powerful current.
In rural conditions, the mass switch cannot be found at all. Under Soviet rule, it could have been unscrewed from some old tractor or lawn, but now this is unrealistic.
After conducting several experiments and roughly calculating the currents and load power during the operation of a car starter, I began to apply for this purpose .... conventional 220V circuit breakers from electrical panels. The subtlety lies only in the fact that you need to find a machine at 63, 80, or 100 amperes. I tried to set the machines at 40A and 50A, but sometimes they can not withstand inrush currents and turn off. In this way, I installed mass switches on many models of machines.
Here, for example, the photo shows the installation of such a machine in an old NIVA. For clarity, the lining and sound insulation are removed.
The standard mass wire goes from the battery through the hole in the body to the machine from above, and the elongated mass wire purchased at the store is screwed into the machine from below, and the other end of this wire, with a large terminal, is screwed to the engine.Another wire from the battery, with a small terminal, is screwed to the car body.
Something like this. Simple, inexpensive and reliable.
An indispensable condition when installing the mass switch: it must be in the passenger compartment in an inconspicuous but convenient place. Installing the switch under the hood or near the battery does not make sense, because if something closes, and God forbid, it lights up, you simply will not have time to open the hood and run out.
