For those who own Ventus Cm: have you ever measured the voltage on the starter when it is running?. Mine, with fully charged battery, while electric starter is running, voltage on battery fall out to 10volts, and on starter I measured only 6 or 6.5 volts. I have a voltage lost of aprox 2 volts over the positive wire and 1.5 over the negative one. Is that normal? I have starting troubles sometimes and i think it is because of it. What can you tell me about it?


Ok, Thank you all for your replies and advises again. I´ve made all kind of measurements. No bad connections, no bad relay, no bad battery and starter is brand new. NO hot spots, no weaks connections.
I disconnected everything and check all the contacts and terminals. It seems the drop of voltage was mainly on the wires due to its length and age. I finally installed a second complementary 10mm2 wire all the way from battery to starter and back with negative wire. (it is impossible to remove the original wires without having to dismantle all the glider)
Now, when cranking, battery voltage drops from 12.7 to 10.5 but on starter terminals I measured 7.5 Volts. With this, the starter runs to much faster and the engine starts as easy as when I supplied energy from the car with the car emergency wires. Never, since I have this glider, it cranked as fast and started as easily.
Anyway, if someday someone has the opportunity to measure the voltage on the battery and on the starter while cranking, please let me know. I really would like to compare my glider with someone´s else. THANK YOU very much.
