bosch relays

[Tim]

has anyone heard of the bosch relay book put out by DLC, show just about any conceivable wiring diagram for using bosch relays! its a great book, especially if you own a Wanderlodge

Mr. Tim,

Is this what you are looking for?

[Tim]

yes, I have it
and was just gonna share it with every one, if they'd never seen it, has great wiring diagrams for doing stuff you never thought about, Ive had a printed copy, used it for years

[Tim]

whats that Ed McMann used to tell Johnny, everything you ever need to know about using bosch relays is in this book

OK, Bosch (now TYCO) relay fans, that book in PDF file form has been in the Database for quite some time, I found it in about 30 seconds by doing a "Search" of the word "Bosch", it can be found at;

In our birds Bosch relays can be used anywhere where you want to increase the voltage and current to a device such as your headlights. On one set of contacts you connect 12VDC from your battery thru a circuit breaker using a larger wire to the low beams and another bosch relay with 12VDC going to it with a larger wire to the high beams. Then you use the dimmer switch on the floor (or where ever else you want it located or where BB located it) to apply the "trigger voltage" to the Bosch relays to turn on the 12VDC to the headlights.

Using this same method of using Bosch relays you can then take all of the high current circuits like the A/C fan motors, ignition switches etc out of the dash and only use the switches in the dash to "trigger" the bosch relays to provide the higher voltage and current to the fan motors and ignition switch circuits. Once you understand how easy it is to connect the Bosch relays it becomes easy to connect any circuit in your coach to a Bosch relay and even remotely control it.

Another good place to use this relay is for the water pump.
Most newer pumps require more power (voltage x current) than older pumps. Delivering more current, can require heavier wires.

I installed the 5.7 GPM unit from Aquatec with a Bosch relay and 10 gauge wires from a good source. The old pump feed was used as a trigger. The ground was switched in my case.
