I believe the only problem would be if the connections of the main alternator and battery feeds through the bulkhead connector (assuming you have one) are marginal. Occasional increased current through the alternator feed and back to the battery could cause a marginal, deteriorated, originally undersized connection to overheat with serious effects. The Voltage regulator controls the feed to the alternator field to control output Voltage and should not be affected by higher current elsewhere in the system. Among the many things I don’t know is whether a higher-Amperage alternator will produce more current at idle than a lower-Amperage alternator. If so, that might better support electrical load and minimize battery drain while stopped in traffic with a heavy electrical load.

The unit on my car is 30 amp. I have a 40 amp unit that I want to install - any problems - voltage regulator, etc?
