SOURCE: charging problem 1991 volvo 240

14.6 means your voltage regulator or diode is suspect Despite having new alternator .Ive cross refrenced your smptoms in the haynes workshop manual and alternator is your only end answer.The haynes test is to start vehicle with multi meter connected across the battery terminals,increase the engine speed until the reading remains steady should be approximately 12 to 13v and no more than 14v.switch on as many accessories as possible(headlights heater blower radio etc)check that the alternator maintains the regulated voltage at around 13 to 14v.If the regulated voltage is not as stated then alternator is to be repaired/replaced.Good luck with it and a happy new year.

SOURCE: Air Conditioning of my Renault Megane is not

Hi

Have the driver's door window open and the front bonnet open,
we are going to listen for a clicking noise, the noise that we are listening for is the Compressor engagement being activated after three seconds from the control panel.

Start the engine and switch on the air conditioning by pressing the AC button (with a request for maximum cold temperature and the passenger compartment fan running).

If you hear that clicking noise, then it is most likely that you have a leak from the AC system or a possibly in need of a top up do to service of the system not been carried out.

Otherwise if you don't hear that clicking noise then there is a case that the Compressor clutch is not being engaged.

Do to the following reasons

1. fuse blown in the UPC in other terms the fuse box (engine compartment)

2. AC Compressor faulty

3. AC pressure switch faulty

4. If there is not the slightest bit of pressure left in the system which is very unlikely.

I hope this information was somewhat helpful for a real diagnosis test a diagnostic tool is needed.

Enjoy.

How do I fix starting problem in Megane 2004 1.6 16v


Sounds as though there is a charging problem with the car. It starts when battery fully charged but when the charge is low it fails to start. I would get a mechanic to connect his meter to the battery and see if it is charging as it should. It is also possible that something is draining the battery when not in use. Check interior lights are going out when parked up, nothing is plugged into cigarette lighter outlets attached to sat nav etc., things like that.

Sounds like it could be the linkage. Check to be sure the mechanics are still connected. If so, then you're clutch may need to be replaced.

RENAULT MEGANE AIR CONDITIONING


The most common cause is a leak in the system and a low refrigerant charge. Have a set of AC gauges hooked up and see what the system pressure is on the low side.
