But to test, or to get the indicators to work in an emergency pinch disconnect the flasher switch and jumper pins 15 and 49 on the connector, pin 49 supplies 12volts to the directional indicator relay. Please note that there may be several green/red (or green/orange) wires coming from the back of the dashboard, so make sure you get the one that comes from the indicator tell-tale light. The flasher receives power from one of 2 fuses, the Stop light switch. However my question is do i already have a diode wired in for it to have been working for some time and only now just started the hazard lights thing? Let's take a look at how the turn-signal circuit is hooked up. Flashing LEDs take the basic form shown in Figure 7 (b) and have a built-in integrated circuit that gives the flashing effect. In practice, the actual mean current consumed by a micropower LED flasher circuit is equal to the sum of the LED and the driver currents, and is inevitably higher than the minimum figure indicated above. endobj lights and they are /SA true Set the digital multimeter to DC voltage current. These multi-part series may be just what you need! Figures 18 and 19, for example, show two alternative micropower LED flasher circuits that when powered from 6V supplies consume total currents of 86A and 12A, respectively. First Things to Check: Most electrical problems can be easily fixed by checking the following: The fuse box. for In others, there might be a switch you have to pull (usually in older vehicles). Return from Turn Signals to Hot Rod Wiring to the Kind regards, James, Hi. Direct connection LEDs are designed to be connected directly across a fixed-value DC or AC voltage source. FIGURE 19. Is this some sort of custom setup you have? FIGURE 8. thus One of the cut wires will be used to make a new ground connection (see the next step below), so give some careful consideration to where best to make the cut before actually cutting the wires. The switch connected both rear lights to the flasher and simultaneously connected a relay to the flasher. Now wire it in like this. The composite diagram is shown here: 1) Power for the flasher is shifted from Term #15 to \hW+l% ajH4aA|-a.L'o$)EQ)?V_6( V W8/}cE]!^R!
