High Output Alternator Recommendation – Jean, on Nov 30, 2014 asked:

Can you recommend an alternator manufacturer? I would like to install a 150A unit. Do I have to change my wiring between this new alternator and my house bank? I imagine I will have to change the fuse also.

When implementing alternator output upgrades we recommend the following:

  • Balmar or Electromaax alternator that is high output at low rpm
  • Balmar alternator regulator
  • Pulley kit might need to be installed to drive anything over 90 amp. This will switch you drive from v-belt to serpentine. Serpentine is the best option.
  • You’ll need to change the DC wiring between your alternator, both positive and negative to house bank, including the fuse.
