Hi all,
I found a source of stud type silicon diode rectifiers at a local surplus outlet. I chose 200V 6 Amp stud type to try. I installed one in my ZW 250 on one side to replace a failed copper oxide disk It works like a charm. The whistle on all of my tenders is quicker to react, clearer & much more reliable.
Opinions? I could have purchased higher voltage/amperage. The cost $0.50 to $1.00. Is it really necessary to buy 600V 40 Amp rectifiers? I read that the only time that the high voltage/amperage is needed, is in the case of derailment when the whistle is activated.
