High Charging Rate. Found Voltage Drop Need Guidance Please
^^There are variations in some relays so be careful. The "usual" bosch is call spdt which means "single pole" which is one switch/ contacts set, and "double throw" which means a center contact engages one of two contacts, one at rest (no coil power or normally closed) and one when powered (center contact engages normally open contact)
Also many of these relays have an internal anti-spike diode so the coil is polarity sensitive or you will blow up the diode or damage the control wiring
So ground 85 or run it through a hidden switch to ground and that will create a SIMPLE ANTI THEFT device.
Connect 86 to the "ignition run power" coming out of the bulkhead connector
Connect 30 to power through a big fuse or circuit breaker say 20-30A coming from your starter relay "big stud"
Connect 87 to the underhood loads
THE GLITCH BE CAREFUL!!!!
Most relays, you want to leave 87A UNconnected.
But some relays have 87 and 87A in parallel for more current. The ones I have see have special larger terminals and are "obvious" this way as well as having a diagram on the relay indicating such.
