Diode Board / Rectifier
- Designed to replace the original Bosch Diode Board with modern EnDuraLast technology - With 6 x 60 Amp silicone wafer Diodes / 3 Negative + 3 Positive.
- Modern Technology Manufactured Diodes update this old design to provide the latest in reliability and endurance under increased current demand and high heat conditions.
- The press fit diodes dissipate heat thru a close tolerance interference fit with the heat sink .
- Not soldered to heat sink / heat dissipator, which can melt and loose heat dissipation ability.
- All other connections use high-temp solder.
