Coronary Disease Cables Starter

My starter dynamo often do not work when the engine is hot, such as when a new arriving home after a walk, a dead machine can not be a started again. Or were the streets, stop at the mini market, a dead machine can not be started again when going away. Initially suspected dynamo problematic, and indeed the dynamo along with solenoid switch is problematic and repaired:

The results are very nice improvement. Starter work when engine is cold but it still will not work when the engine is hot. Allegedly there is a problem in the wiring, well as humans get older sometimes affected vessel (coronary heart disease). In the old cable, too. A young cables still up resistance when the heat rises, the old wiring worse rising :).

Resistance equation:

R = Ro * [1 + K * (T-To)].

With Ro = resistant value when the temperature is 0 degrees, for example (usually at 20 C)
              K = coefficient
              T = temperature measured
              To = temperature of 0 degrees, for example (usually at 20 C)

sample graph:

On old cable, the K value may be too large, so a change of 25 Celsius to 75 Celsius for example, can lead to resistance rising dramatically (vessel narrowing) and drop a lot of current flow hence not able to turn the starter solenoid switch. Solenoid suck large current, its  up to 30 A.  Ampermeter needle rocking in time starter, but there was no sound of solenoid work. If there is no ampermeter, I also did not know what was happening. The big movement of the amperemeter needle indicates there is a large current entrance to the solenoid switch but the starter solenoid does not work properly. This means that the solenoid such as lack of sufficient current to make the solenoid work.  Current flow blockage occurs when the engine is hot.

The solution:
1. Push the car to turn :), or
2. Relax first, smoking and wait for the machine and the cord  cold, or
3. Replace the new cables, contact wires and Bendik cables , or
4. Remove the old cable functions to the new cable through the relay.

My solution  is No. 4. Yesterday I installed relay and on the next day, i drove through worn-congestion jam along Arcamanik-jl Jakarta, 1/2 temperature, because less stationary, the engine had died seven times. Fortunately engine work every started because coronary disease has been cured wear relay.

Here's how to install relay:

Materials needed :

1 pc relay Hella 30 A

1 pc holder relay

2 m cable blue 3 mm

2 m cable dark blue 3 mm

1 m cable yellow 3 mm

5 pc Female terminal

1 terminal male

2 terminal to the battery


Good luck.
