Questions & Answers
Is this a genuine Iskra part?
This is a premium quality 4Drive aftermarket replacement part, manufactured to meet or exceed original equipment standards for commercial durability.
Will this work with a 12V system?
No, this is specifically a 24-volt alternator for heavy-duty commercial and plant machinery. Please verify your system voltage before ordering.
What if my original unit is 80A?
While this 55A unit is a standard fit for many B10 series, some specialized bus configurations require an 80A or 100A unit. Please verify your current alternator's plate to ensure 55A is sufficient for your application.
