Bosch 30019 12V Voltage Regulator for VW Beetle

Working well with the original generator, I use it on my Massey Ferguson 135 tractor. When rpm is low, voltage will be around 13V, but will rise to 14V when rpm is high. The generator's "A" is D+, the DF is "F", so there is no need to connect an indicator lamp unless you want to. Be careful with the metal case, as it is around 12V, so keep your hands off the mass (ground). A generic wiring diagram that I found on the Internet is attached.

A 1971 Super Beetle with erratic charging bounced from 11 mph to 18 mph. Putting 2v to 12 in your own words This can drain the battery over multiple days when the battery voltage is 8v. It was time to replace the generator brushes. The lower brush is a hassle, but the charging was still erratic and the generator light always lit up. We were able to install this regulator in 30 minutes and it was a direct replacement for our own. I started the generator and the light finally went out when the Beetle started. We now get to see a very stable 13 when driving down the road. There are at least 5 volts, even when the headlights are The part is a good replacement.

As soon as I ordered it, I received it. Identical wiring is used on both the Bosch mechanical regulator and the Bosch electronic As it was over twenty years old, I didn't see the labeling until I removed it. Once I realized that the connections were in the same spot, it took me a while to get it installed. There is often a temperature rise at night in Florida up to 130 degrees I don't know if that is normal. Please let me know if operating temperatures are normal. When I installed it, I also installed a new, unnecessary distributor, which ensured that the voltage would be steady. As far as I can tell, the combination has been effective.

In spite of purchasing 5 voltage regulators from a variety of local parts stores, and replacing the generator twice, I have determined that the regulators from China are There is a chance that all were made by the same manufacturer. You will not be able to get the results you want if you Don't waste your time on other gadgets just buy a Bosch. The first time it was used, it worked perfectly.

Earlier today, I installed this voltage regulator. It is stable at this voltage level. A voltage of about 13 volts is measured at 3000 rpm. This is a good reading without any spikes or high values. Previously, I was using a different brand and had several issues with it. My generator is cool to the touch. I will keep it with Bosch for years to come. Voltage may get too high, which will result in a hot generator. the battery voltage drops too low, the battery will fail. 35 volts are produced by the generator and 12 volts by the battery. Using this regulator, you can achieve a result between 5 and 13.

My 1970 Volkswagen Beetle was the perfect fit for this. A Bosch part was not available in my local parts store, so I ordered one online instead. This product is fantastic for the price I paid. It arrived fast and is well-labeled. It was extremely simple to install after I bought it on Amazon. My Bosch part arrived quickly and I am back up and running with a part that I can depend on for years to come.

It has lasted longer than two old style voltage regulators I was using on my dune buggy, and this one is now sticking to me through all the abuse I can dish out. I don't think it's fragile at all. Do yourself a favor and purchase this one rather than the crap down the street.

You won't find any instructions in English, but you can figure out how to use it.
