FUSE PANELS and handlebar switchs
 

 

This is a picture of a fuse panel that I made when I first started making my own trikes.  I don't use it any more as there are some real nice fuse panels on the market that do the job better.

 
 

The Relay

Click on relay for the catalog to order.   Type "Relays and sockets" into the Quick search box.
 

SPDT Relay  : (Single Pole Double Throw Relay) an electromagnetic switch, consist of a coil (terminals 85 & 86), 1 common terminal (30), 1 normally closed terminal (87a), and one normally open terminal (87).

The Auxiliary Fuse Bocks
 

 

The Buss 6 circuit 30-amp fuse block is used due to it's low profile and it uses ATC fuses.

 

ATC Fuses are available in 9 amperages:
3, 5, 7.5, 10, 15, 20, 25, 30, & 40.

 

 The fuse block I  use is found at most marine boat suppliers.  What I like about this set up is that there is a provision for ground wires at one end. Here is a catalog shot of it/them depending how many fuses you want to have.  Click on the picture to go to the supplier's web site. Type in the model number to go to that page.
 

 

I found another type you could use.    This type you could  mount them to the top of your tank.   Fuse replacement is easy due to the removable cover.
 

 

FUSE PANEL WIRING
 

On relays with diodes in them # 85 is the normal 12vdc input and #86 is normally the ground.  However, if there isn't a diode in the relay it doesn't matter which is which.  If you don't know if your relay has a diode or not put wires to #85 and #86 and touch one to the positive side of the car/trike battery and one to the ground side.  Then do the opposite.   If it clicks on both then you do not have a diode in the relay.    None of the relay I use have  diodes. 

All relays perform some type of electrical switching function.  They can range from switching very high loads to switching multiple tasks.  They may be used to isolate electrical tasks or to combine them.  It is always wise to use relays in combination with handle bar switches as the wiring in these switches is very small and could fry if large  loads are put through them. 

All your 12vdc input wires can be run from one source, linking one relay to the other.  Grounds also can be linked.
 

Shown below is the basic set up for use of the relay

TURN SIGNALS
 

Turn signals:  I use the Badlands Automatic Turn Signal Shut Off Module.  This unit is simple to install and has instructions for OEM and custom bikes/trikes.  Features include:  Nine second timed flashing that automatically cancels.  Can manually cancel any time.  Has a built in emergency flasher mode.  Measures 2 7/8" long, 1 3/8" wide, 7/8" deep.  I got mine at Jireh cycles  Type in part number 17-110 in the search engine.

 

If you decide not to use the Bandlands turn signal module, shown elsewhere on this site, use a heavy duty turn signal flasher unit (2 prong)  Run a fused wire to the flasher unit and from the other side go to the center pole of your turn signal switch.  Then follow the wiring diagram.

ANTI-THEFT (Starter disable divice)

On my trike the two fused wires come from the fuse panel
 

 
 

Sensible Wiring
 
All of us are concerned about wiring our trike or car properly. So much in fact, that I’ll bet most of you engineer to overkill. What are the issues you need to be concerned about?
