in-line (if, for instance, the battery must be removed for any
purpose and A.C. is still available). All but the most sensitive D.C.
powered electronic devices will function as normally as if powered
by a battery. In addition, the current limiting circuitry enables
the charger to handle the high start-up surges associated with
inductive loads, such as D.C. motors in radar sets.

VII TROUBLESHOOTING
Note: The PT 80, PT-24-45U, and PT-=24-95U chargers incorporate a self-contained A.C. to D.C. conversion module which utilizes
numerous automatic protection circuits. The A.C. input and D.C. output fuses which protect internal wiring are housed inside the charger
module. Under most circumstances these fuses will fail only if the charger has an internal fault. Hence, they are not intended to be
user-replaceable and any condition which has caused a blown fuse will likely require repair of other internal circuitry by a qualified
technician. If an apparent charger fault cannot be corrected using any of the recommendations in this section, the charger should be
returned to the factory or place of purchase for inspection and repair or replacement.

Problem Possible Cause Solution
A. Batteries not coming up to full
charge
1. Extremely discharged batteries requiring
long recharge time
2. Charger limiting its output due to overload
or over-temperature conditions
3. Fan not operating properly, causing
charger to over-heat, reducing or ceasing
power output
1. Turn off all D.C. loads and allow charger 24-48
hours to recharge batteries
2. Reduce D.C. load and/or determine cause of over-
temperature condition (see section III-B, Location)
3. Check to ensure there is no blockage at fan intake
on bottom of charger. Replace fan if necesssary (see
section IV-G, Cooling Fan)
