Alternator Upgrade for Hybrid Robot

Driving "Roberto the Robot" on low and or almost dead batteries does not make for a very fun experience. In order to correct this problem, I decided to install an alternator on the top deck plate. Therefore, when the 6.5hp engine was running the batteries would charge and the robot would operate as usual. The alternator I used is a 120 amp Deutz Letrika alternator from Surplus Center. 

Below are pictures of the setup. If you have any questions please leave a comment below or email them to me at [email protected]
