New offences

The new offences that will now draw penalty points include:

  • Failure by learner or novice drivers to display L plates or N plates respectively on their cars;
  • Drivers breaking a ban on U-turns;
  • Breaking rules on the use of mini roundabouts;
  • Offences relating to the size and weight of larger vehicles;
  • Going beyond no-entry to vehicles signs;
  • Disobeying traffic control signs;
  • and driving without a licence plate or with one that has been altered inaccurately.

Offences that will now face a change to the number of penalty points they now carry will include:

  • Driving without a test certificate; 
  • Dangerous parking;
  • Failure to keep to the left-hand side of the road;
  • Dangerous overtaking;
  • Driving across the road’s middle line;
  • Failure to stop for a stop sign;
  • Failure to yield at a yield sign or yield line;
  • Not following traffic signs at junctions;

  • and breaking of speed restrictions.

Smart Charge Testing And Description

06 December 2014 - 01:33 AM

Theres a lot of topics on smart charge so this is a guide to testing the system and how it works

First things first, check the battery, not just condition, but correct type. A lead acid battery will not work properly with smart charge, it must be Silver Calcium! Easy to over look.



Next, put a meter across the battery. Remember when you remove the smart charge 3 pin plug from the back of the alternator, it reverts to a conventional alternator! If you do not have about 13.8 volts, carry out basic charging system checks and suspect the alternator, its not a smart charge fault !



Correct charge voltage from the alternator, then its time to start on the smart charge system, and you will need a scope. First the system.



Pin 1 = Alternator Feedback

Pin 2 = Alternator Load Request

Pin 3 = Reference Voltage



Now, pin3, must MATCH battery voltage ! Its fed from a fuse in the CJB, and a high resistance on the fuse contacts causes a volt drop, and the smart charge drops out !



Next pin 1 & 2 need checking back to the PCM for resistance, isolation from ground and each other. If ok, its out with the scope.



Pin 2 is the request from the PCM to the alternator. This will be a square wave pattern that will change with load request. So lights, screens etc on and monitor for a change in the pattern. (Obviously back probing with the plug connected)

No change in the pattern means no request from the PCM, you should now suspect a PCM fault. Correct pattern and move on.



Pin 1 is the feedback from the alternator and MUST remain a constant square wave pattern. If this pattern mirrors the one on pin 2, the smart charge part of the alternator is faulty, and a new unit is required.



With these simple checks, you should always be able to diagnose a smart charge fault.



Another point to add is, never, ever, jump start a Smart Charge vehicle with a flat battery.



The system can produce up to 18 volts, which can fry major modules.



The theory behind smart charge, is a battery will take a charges at its most efficient when its cold. Following start up, the PCM checks the Engine coolant temp, and intake air temp, and calculates a cold engine. It will then boost the battery charge, pulling it back as it calculates the under bonnet temp coming up. Its not there to compensate high demand as is the common misconception.



The problem comes on a jump start, when the PCM sees a cold engine, and then a poor battery condition, and can then instantly zap out about 18 volts because its trying to recover the battery. Unfortunately this sudden surge can cook modules.

Headlight Wire

17 September 2014 - 11:07 PM

Okay guys ive got some leds im wiring up but to come on when the headlights come on i had a diagram from an old post on here of what headlight switch wire to tap into but ive lost it so any help would be appreciated

Osram Cool Blue Intense

25 March 2014 - 08:09 PM

after reading so many posts about these bulbs i bit the bullet and bought them and i have to be honest guys they arent what i expected from the reviews i use these bulbs http://www.ebay.co.u...=item4d08688f4c

 

which i have to say are as bright but much whiter than the osrams and since ive had them over a year will likely last even longer yet for the price of the osrams i got that entire kit which has all passed an mot the only change is the sidelights which were replaced with diamond white ones the osrams are still yellow compared to the above bulbs

 

not a fan and they certainly dont prove that a brand name is better im going back to my old bulbs and sending the osrams back
