B+ goes to positive on the batteries (preferably via a main fuse).

B- goes to the negative of the batteries and the starter motor and any earth points.

D+ receives a magnetising current when the generator starts.

Some generators also have W which is the tachometer socket and DF which is in direct contact with the magnetising winding of the rotor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

If you have a reasonably large bank<\/strong> with a daily discharge of 25 per cent, you will be able to oscillate in equilibrium between 60 and 85 per cent using only your generator. If you install a small solar panel too, the curve moves up a bit. That’s even better for the batteries.<\/p>

If you have a poor connection, more batteries won’t help<\/strong>
A large battery bank will help for the first few days even if your charging is poor<\/strong>. However, bad connections, scarred cables or faulty diodes can leave you at dangerously low levels after just a few days<\/strong>.<\/p>

So if you decide to just<\/strong> spend money on a large battery bank, it can be a costly affair as the lifespan of the batteries can be short if the charging does not work properly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
