Draw-tite Electronic Brakes Lights Stays Off No Power?
Virtually electric trailer brake malfunctions, that cannot be corrected past either brake adjustments or synchronization adjustments, can more often than not be traced to electrical organisation failure. Voltmeters and ammeters are essential tools for proper troubleshooting of electrical brakes. Mechanical causes are normally obvious i.e. bent or broken parts, worn out linings or magnets, seized lever arms or shoes, scored drums, loose parts, etc. Replace defective or worn parts.
How to Measure Voltage
System voltage is measured at the magnets by connecting the voltmeter to the 2 magnet atomic number 82 wires at any restriction. This may be accomplished by using a pin probe inserted through the insulation of the wires. The engine of the towing vehicle should be running when checking the voltage so that a low bombardment volition not affect the readings.
Voltage in the system should begin at 0 volts and, every bit the controller bar is slowly
actuated, should gradually increment to about 12 volts. If the controller does non produce this voltage control, consult your controller manual.
The threshold voltage of a controller is the voltage applied to the brakes when the controller kickoff turns on. Lower threshold voltage will provide for smoother braking. If the threshold voltage is too high, the brakes may experience grabby and harsh.
How to Measure out Amperage
System amperage is the current flowing in the system when all the magnets are energized. The amperage volition vary in proportion to the voltage. The engine of the tow vehicle should be running with the trailer connected when checking the trailer braking system.
1 identify to measure arrangement amperage is at the Bluish wire of the controller which is the output to the brakes. The Blue wire must exist disconnected and the ammeter put in series into the line. System amperage draw should be as noted in the following table. Make sure you ammeter has sufficient chapters and note polarity to prevent damaging you ammeter.
| Brake Size | Amps/Magnet | Ii Brakes | Four Brakes | Half dozen Brakes | Magnet Ohms |
| 7 x 1 i/iv | two.5 | 5.0 | ten.0 | 15.0 | 3.9 |
| ten x 1 1/two | three.0 | 6.0 | 12.0 | 18.0 | iii.two |
| 10 x 2 i/4 | 3.0 | 6.0 | 12.0 | eighteen.0 | iii.ii |
| 12 10 2 | 3.0 | six.0 | 12.0 | 18.0 | 3.2 |
| 12 1/4 x 2 one/2 | three.0 | 6.0 | 12.0 | 18.0 | three.ii |
| 12 1/4 10 iii three/8 | three.0 | half-dozen.0 | 12.0 | 18.0 | 3.two |
If a resistor is used in the system, it must be set at zero or bypassed completely to
obtain the maximum amperage reading. Individual amperage draw tin can be measured by inserting the ammeter in the line at the magnet yous want to check. Disconnect one of the magnet atomic number 82 wire connectors and attach the ammeter between the two wires. Make certain that the wires are properly reconnected and sealed later testing is completed.
The almost common electrical problem is low or no voltage and amperage at the brakes. Common causes of this condition are; poor electric connections, open circuits, insufficient wire size, cleaved wires, blown fuses (fusing of brakes is not recommended), improperly performance controllers or resistors.
Another common electrical problem is shorted or partially shorted circuits (indicated by abnormally high arrangement amperage). Possible causes are; shorted magnet coils, defective controllers or bare wires contacting a grounded object.
Finding the crusade of a short circuit in the organisation is done by isolating one department at a time. If the loftier amperage reading drops to zero by unplugging the trailer, then the short is in the trailer. If the amperage reading remains high with all the brake magnets asunder, the brusque is in the trailer wiring.
All electrical troubleshooting procedures should start at the controller. Virtually complaints regarding brake harshness or malfunction are traceable to improperly adjusted or nonfunctioning controllers. Run across you lot controller manufacture's data for proper adjustment and testing procedures. For best results, all the connection points in the brake wiring should be sealed to prevent corrosion. Loose or corroded connectors will crusade an increase in resistance which reduces the voltage available for the restriction magnets.
