Hello Everyone I have a 2007 corolla 141. My service was due next month and I went for the full service today. I did my service from a service station that I have done twice before. Then today afternoon (around 5pm) I went there to take back my car home after they said service is completed. I started my car to reverse and suddenly there was some tightness with my steering wheel. I Restart the car and tried to reverse again . Same tightness appeared in the steering wheel again. Then I complained to the service station people about the issue. They told me to take the car to the 150m away Gurage and they called them I will come. So I drove my vehicle there with very difficulty because steering wheel was very tight and i couldn't drive it smoothly with cross roads. While I just came to the Gurage location my dash board indicators became blinking and My radio switched off automatically. Just after I drove my car inside the Gurage car automatically stopped and didn't start gain. Then technician came and did a Jump start. I was there when he check the issue and one terminal of my car battery was moving/loose. He did a jump start after tightening it and checked the alternator voltage. It indicated only 7V and he told me it should be 12V. Car battery was not charging by the alternator. He told me he will have to check the alternator tomorrow morning as all these incidents were happened and it was 7pm. He gave me indication that it may be alternator has gone (may be burnt what he meant I think) or may be a diode or something can be and will have to check tomorrow (12th) . Please help me out guys what may be causing this ? Will I have to replace the alternator, If so how much will it cost ? Is it available in Matara area ? Will I able to repair this tomorrow because its new year after

On behalf of a friend who's looking for a SU14 alternator, Please see his request:

Hi All, This is something happened to me recently and I thought this might be useful for others as well to simply solving sudden engine cut-offs or misses that stops the engine and to get an actual understanding of the issue. My alternator belt was giving a shrieking sound here and there and since it was newly replaced at U***O, I just asked them to have a look. They identified the issue as the belt being too loosed and tightened it. Once the engine was re-started, it started to cut the engine off! As soon as the foot was taken off from the accelerator it stalled. The first thing they did was to connect the diagnostics, and run through the engine under the assumption that the fuel pressure was low. But, since the vehicle was running so smoothly without any issues from the morning, I just made an inquiry related to the alternator belt tightening, which turned out to be the real reason for the engine stall. When the belt was loosened somewhat, the issue got solved! When inquired, the mechanic said, the same symptoms were shown in another GDI they repaired recently, and that the issue was with alternator handling the load. Well I could not exactly make head or tails out of this answer on how it stalled the engine. How does the tightness of the alternator cable stall a well performing engine?

Hi Experts, This is regarding an alternator enhancement. I have gone through many articles and posts such as http://www.google.com/patents/US5874822 to find out how an alternator can be modified to provide more power without going to replace the whole unit. (Keeping housing and brackets as original) The major part that most people replaced is the Stator. With a higher AMP stator for the existing alternator will increase the power that it produces. But I couldn't find any related article about Stator replacement efficiency comparison with RPM ratio. When it comes to diesel engines, the idle RPM is bit lower which could be 500-600. By supposing that we can increase it up to 1000 or 1100 by changing the pulley system, is it possible to have a higher amp stator for exising rotor? Kindly need advises from your practical experiences. Thanks.

Hi experts, I kindly need your advice on the following matter. What makes it possible to increase the amount of amps produced by an alternator of a Mitsubishi 4DR5 J44 jeep? I got few suggestions and will list it as; 1. Rewind the alternator 2. Re-size the pulley (I think to make it fast) I do not know any of those are practical. However without replacing, what ways I can think of getting more power from the current alternator? I really appreciate if you could share the experience. Thanks. PS: With the load of AC, Headlights and other electrical stuff, it seems there is more power needed. However I didn't test properly and looking for ways that I can follow if in case a higher amperage is needed. Therefore your replies are highly appreciated.
