Mercury Bobcat Voltage Regulator
The Voltage Regulator on the Mercury Bobcat keeps its charging system safely between 13.5 and 14.5 volts so the battery and components don't get damaged. It detects battery state and total power demand, then adjusts alternator field current to boost output when lights or other loads pull voltage down and to turn output down when charge goes up too high. The early models of Mercury applied an external, mechanical Voltage Regulator with coils and contact points which switched on and off approximately 200 times every second. These designs suffered from point wear which could lead to overcharging. Subsequent Bobcat models were equipped with a solid-state electronic Voltage Regulator that replaced moving parts with transistors that could take about 7,000 rapid corrections per second for steadier voltage and greater durability. As technology progressed, many systems migrated to using an internal Voltage Regulator built into the alternator, and on newer cars the PCM now controls charging while still following the same basic principles. Over the years, Mercury and Bobcat owners experienced a rapid response, easy wiring, and better reliability. The Voltage Regulator is today's key to every Mercury Bobcat start and mile, and it should be yours.

Mercury Bobcat Voltage Regulator Parts Questions & Experts Answers
- Q: What is the purpose and test procedure for an independent voltage regulator on Mercury Bobcat?A:This type of voltage regulator is stand-alone and is situated inside the engine compartment; it can be either mechanical or electronic, based on the date of the vehicle manufacture and its type. The mechanical type is a closed-unit with no settings; in case it is suspected faulty due to battery charging problems, a voltmeter check can be performed by attaching leads on the battery terminals and observing the reading with all the electrical loads switched off. The engine should be started and idled at 1800 to 2200 rpms for few minutes with the voltmeter reading as expected to be 1 to 2 volts high than the starting reading. If the difference measured is less than 1 volt or is more than 2.5 volts then it is probable that the regulator is defective and needs to be replaced. For the electrical loads, a drop of not more than one volt when they activate should be observed; if not, then the regulator should be replaced. Before disconnecting the voltage regulator, battery current should be disconnected and if the regulator is placed behind the battery the battery should be shifted towards the front side. Like in the electro-mechanical type, voltage regulation is done by transistors and diodes but the levels can be adjusted if the regulator has reached the normal temperature. It should also be noted that adjusting screw must be rotated with an insulated tool, as in the case of the mechanical type of the unit. The electronic type, which is available in the later models, is enclosed, and should not be disassembled; when it has a problem, the entire assembly has to be replaced. In particular, it is necessary not to connect an old regulator to a new alternator, and there are individual rules for working with sealed electronic regulators: check the correct connection and connection before testing or adjustment.
