I put a rebuilt alternator and new voltage regulator on my skid steer with a Kubota diesel. I also put new batteries in. Lots of problems getting a voltage regulator to work right. Eventually took to the place that rebuilt the alt. and they said they just hooked up a regulator and it worked. The dash light stayed on so they took one wire off and said it's OK. At the time(about 3 months ago) it was putting out close to 15 volts which they said was OK cause the battery might have been low. The alternator also got pretty hot. I've only used the machine a few hours since then but had to bring it to the city for snow removal. It started right up and the charging light went off. I had it running for about 35 minutes while I hooked up the trailer etc. I noticed a smell of battery acid and checked the output voltage. It was 16.78! I put the machine on the trailer and brought it home. I checked again and when first started, the voltage was around 13.4 and slowly went up close to 17 again. The battery's had lost some fluid as well. I spent over $250 for the alt., regulator and to have them hook up a regulator that they said was fine. Plus I bought 2 new batteries. I had a bigger style regulator that lasted over 10 years and this machine was known for regulator issues. They say the larger style regulators aren't available but won't phone the supplier. I'm taking the machine there Monday. Anybody have an idea what's wrong? It's a 25 amp Nippon Denso alternator with external regulator. Could something in the alt. be bad? It's very frustrating. Dave
