  Q: How to replace the alternator brush and voltage regulator on Hyundai Excel?

  A:

  This guide only applies to the models made between 1986 and 1988. To replace the voltage regula-tor/brush assembly, the Alternator must be completely disassembled - remove the alternator and install a new or reconditioned one. If you are replacing the brushes (but not the regulator itself), you would have to take out two screws that fix it in position and pull it straight out. If you do not know how to work with a soldering gun then find someone who does because if you overheat this delicate part of your vehicle, you may end up spending more money than anticipated. Take out the alternator. Remove the two mounting screws and pull off the voltage regulator/brush holder assembly from both of them. Measure the length of brushes on regulator/brush holder assembly. Use a small ruler to measure their length-if they're less than 0.18", install new ones. Replace them with new ones in case they are shorter than required by 0.18 inches. In steps where we will just be replacing voltage regulators, we can skip some like this since such kinds contain new brushes too. Desolder brush wiring connections before disconnecting worn brushes from voltage regulator/brush holder assembly and carefully unsolder brush leads, extract each brush and lead from holder as well as remove both brushes and springs. Install reverse of removal process but ensure that when installing, correctly solder new brush leads are properly done after desoldering brush wiring connections followed by careful desoldering of brush leads; then each brush is extracted along with its lead from holder which is removed together with these items; also remove both brushes and springs; finally re-installation should follow removal method whereby correct soldering has taken place since processes involving installation need correct soldering in order for things such as properly installing plus removing come into play either way as advised after Unsolder the brush wiring connections for example while removing worn out brushes from the voltage regulator/brush holder assembly at the same time carefully unsoldering brush leads followed by extracting each brush and its lead out of holder which shall be taken off together with these components; besides there should also be removal of both brushes along with springs; then reverse process of mount is undergone but take note that reinstallation needs to bear in mind right soldering will occur only when Desolder the brush wiring connections prior or after removing worn brushes from voltage regulator/brush holder assembly while carefully desoldering brush leads as well as extracting each and every brush and its lead out of holder, thus removing both brushes inclusive of springs; at this point installation can now proceed backwards but one thing is for sure, remember that correct soldering should have been done when soldering new brush leads which are properly done by following thereafter careful desoldering exercises involving brush wiring connections over the top first, include others such as placing it in an appropriate position so that you may be able either way as stated earlier after.
