Alternators can be subjected to voltage spikes caused by lithium battery shutdowns, intermittent connections and other over-voltage events. Balmar has introduced a robust Alternator Protection Module which helps protect the alternator’s diodes and internal regulator against spikes (clamping up to 60V) and sustained over-voltage conditions (beginning around 20V) for the 12V version. The APM can absorb multiple surges of such energy, and can absorb surges in excess of 200 amps without failure to continually protect your alternator. Visual and audible alarms indicate if the device has been compromised and needs replacement.

Balmar APM devices provide intelligent, robust, solid state protection in a small, easily mounted package at the rear of the alternator between the B+ and B- terminals. Balmar APM devices can be used to protect all alternator brands.

Balmar Warranty & Returns Process

Balmar Limited Warranty
Balmar’s Limited Warranty covers defects in material or workmanship on new Balmar products generally for a period of two (2) years from the purchase date.  Only consumers or dealers purchasing Balmar products from authorized Balmar retailers or resellers and installed by qualified installers may obtain coverage under Balmar’s Limited Warranty.  Components with a manufacturing date greater than ten (10) years old are not covered under the Balmar Warranty, even if the purchase date has been within the past two (2) years.  Purchases from unauthorized resellers, which may include some online entities, may not guarantee the purchaser will receive a newly manufactured component, and therefore does not guarantee Warranty coverage.

Warranty Resolution
If Balmar authorizes a product to be returned to Balmar or an authorized service provider, Balmar will repair the product or replace it without charge with a functionally equivalent replacement product.  Balmar may replace the product with a product that was previously in service or repaired, but re-tested to meet Balmar specifications.  Balmar will pay to ship the replacement product to the purchaser.  By sending the product for replacement, ownership of the original product will be transferred to Balmar.  Labor charges at the consumer’s site are not covered under this Warranty.  Balmar warrants that repaired or replaced products shall be covered under the Balmar Warranty for the remainder of the original product warranty, or 90 days, whichever is greater.
