Re: 1992 svx with electrical issues
Hello-
Please let me know if you need any in-person assistance. I live in Meadville and have been around svxs for quite some time. Cheers, Mike

The idea of disconnecting the battery and running on the alternator has certainly been around for a very long time, because it originated in the days when cars had no electronic or sensitive equipment. If the alternator is faulty, or the auxiliary wiring to the alternator or connections are faulty, without a battery as a load, the alternator can deliver high voltage spikes, or even a continuous high voltage. As a result numerous electronic control devices are at extreme risk. This is fact not fiction. Members here have experienced and reported voltage run away as a result of alternator regulator failure, and this has proven very, very costly.

You now state. --- “If you don't like it or disagree or feel it is unsafe then don't do it. To me this is starting to sound too much like the arguement for and against light weight pulleys. Some are for it some are against it.” My caution applied in respect of any non charging issue. You describe the test as a check on an alternator which may not be charging, therefore it is logical that a faulty alternator is involved. The fault could be within the alternator and effect the voltage regulation in several ways. An intermittent connection could cause voltage spikes. The external voltage sensing circuit to the battery, could be open, resulting in no voltage regulation. Several possibilities can result in output not being limited to 14.4 volts D.C. Furthermore, in the common event that any diodes in the rectifier bank are shot, the output will involve alternating current. N.B. In this instance there is no argument, simply right and wrong.

Re: 1992 svx with electrical issues
Wow, I see I have started quite a discussion.
Regardless of whether or not it is a valid check, I still felt like, given the possibility that something MAY happen, I would rather avoid it if at all possible. This is why I disconnected the alternator and took it to AutoZone to have them test it, rather than doing something that, it has been argued, has the potential to damage the electrical system of my SVX. I would also advise others not to do it, based on that same risk. Regardless. I have found a clear picture of the other issue I have: The indicated pulley is the tensioner pulley, the bolt behind it that allows it to go up and down (and therefore adjust the tension on the bolt) is what broke. I have a temporary fix in to hold it stable, but I really need the 8mmx1.25 reverse threaded bolt to put back in it :S. |

Re: 1992 svx with electrical issues
Just be careful with those alternators from your local parts store. Many are known to be faulty right out of the box or fail within months. Hence the lifetime warranty or else no one would ever buy them because they know you have to buy 2 or 3 until you get one that will actually last.
