SVE 130 Amp Alternator Limited Warranty
LMR.com warrants its SVE 130 Amp Alternators to be free from defects in materials and workmanship for as long as they remain installed on the vehicle for which they were originally purchased under the ownership of the original purchaser.

SVE 200 Amp Alternator 1-Year Warranty
LMR.com warrants its SVE 200 Amp Alternators to be free from defects in materials and workmanship for one year from the date of purchase. The warranty is only valid if they remain installed on the vehicle for which they were originally purchased under the ownership of the original purchaser.

Any SVE Alternator found to be defective shall be replaced at the sole discretion of LMR.com. This warranty is not transferable and will be voided under the following conditions:

  • Failure due to faulty wiring - including, but not limited to - poor connections, moisture intrusion due to improper connector sealing, shorts due to improper wire routing or protection, and/or improper wire gauge.
  • A faulty Volt gauge or warning system.
  • Improper/negligent installation causing damage to threads, Pulley, mounts, and/or connectors.
  • If LMR.com determines that the alternator was improperly installed or modified in any way from its original design (including but not limited to painting or polishing the case and any disassembly of the unit).
  • Vehicle collision or collateral damage form other failed components.

Pulley Warranty Information
This warranty applies only to SVE Alternators which have been installed in accordance with accepted industry standards by a mechanically competent individual or a recognized service dealer and certified technician. Cost of removal, installation, and incidental or consequential damage are expressly excluded. A warranty claim must be initiated with LMR.com prior to any SVE Alternator return or replacement.

SVE alternator warranty does not apply in cases where the unit was connected improperly, damaged or shorted out by improper use, or failure due to excessive RPM operation. Special finishes are not warranted because we cannot control the use, care or environment of the unit in your application.

When installing this alternator, please use the supplied alternator pulley (or stock pulley if larger. If the supplied pulley is larger than stock, use it, if the OEM pulley was larger then please use it. A larger alternator pulley will slow down the alternator, helping to correct the over-RPM problems. Up to a point, the alternator will compensate electronically for that speed change, so you will not see any significant loss of power.

Failure to use the proper pulley, or underdrive pulleys, can cause catastrophic failure of the alternator, which is not covered under the warranty.

Alternator RPM Calculations
This calculation will help you determine the appropriate size pulleys:
  • You will need to measure: Alternator pulley size (i.e. 2.5") and Crankshaft Pulley Size (i.e. 5")
  • What is your Max engine Speed = (i.e. 5800 RPM) and Idle RPM = (i.e. 1000RPM)
  • Calculate the Ratio, in this case it is 2:1 (5” / 2.5” = 2) or 2:1
  • Then Calculate MAX and Idle RPM: Multiply Max RPM x Ratio (5800 x 2) = 11,600 shaft RPM
  • Multiply Idle RPM x Ratio (1000 x 2) = 2000 shaft RPM @ Idle RPM

We recommend the following:
  • 95A minimum idle 1600 shaft
  • 130A minimum idle 1800 shaft
  • 200A minimum idle 2000 shaft (2200 is ideal)
