has a Balmar ARS-4 regulator
. If you check the PDF from the link in troubleshooting you will see that regulator
provides from 7 to 12 V over blue line to alternator
. From there it goes to instrument panel to Tachometer (engine speed rotation display)
In my case I have 1.2 Volts once the ignition is on and not 7-12.
If I disconnect the blue wire from alternator
I have then around 6V. Anway is much more than 1.2V and I may presume that regulator works fine and that I must repair the alternator. And as fact alternator is not increasing voltage of system when engine
I have one alternator for spare parts
. But I was not checking it for years so I found out today that it was so rusted that rotor was totally stuck. And all bolts did brake when I was trying to open it. Anyway in the end I destroyed everything to get to the diodes. So, ... I think that on my active boat
alternator winding is ok, and that I must have a diodes failure.
If my logic is correct, now I will ask what is the procedure to pull out diodes from the aluminium housing?
Still I can cut them out with grinder. And probably that it would be the less risk of damage.
But maybe I am mistaking. And probably I don't need all 6 of them.
And I was measuring resistance of my spare diodes. And it is around
250 k Ω. Is it a normal reading ?
