Benefits from replacing EVERY Relay and Circuit Breaker G50

[Infinitiguy19]

I replaced the TCS relays next to the battery tray and I notice that at idle the battery voltage went up to 13.6-13.8 volts. Would replacing every relay and circuit breaker with a OEM new one cause any noticeable benefits?

I read a post from Q45Tech that said that replacing the ABS relay would result in a 2 feet stopping difference.

There's no reason that replacing a relay would create an increased voltage, unless the old relay was stuck closed and operating some portion of the TCS system.

The relays and CBs are replaced on as failed basis. And some of these relays/CB are mounted in very tight areas. When I was in the aviation industry (18+ years) we replaced a lot of electro-mechanical components as part of preventive maintenance but none of them include relays/CBs.

Thanks for the replies Heath and Loystock!

I was wondering why Dennis (Q45Tech) said what he said about the ABS relay. I will find it if necessary but I would extremely appreciate if he could come here and explain why relays "Wear out".

And I don't care if he dumbs down the answer or not because I will do my best to understand what he says. I feel confident that I can understand a majority of his posts. Except the one about a math problem proving a theory correct.
