Switching side of the starter relay socket gets full 12v when the key is turned to start. The relay would check good with a meter, but would not supply enough current to run the pump. 50 Starter terminal. With 3rd Gen When the electromagnet isn’t energized, terminal 87 is normally open as it is in an SPST relay, but a second terminal, 87a, is attached to the normally closed position of the internal switch. This kind'a disagrees with the circuit drawing i was referencing: added: i'm going to guess that the "(2)" means it's a two-pole relay, and that circuit is the 2nd pole. 17 Glow plug terminal (Diesel only). - verified pin 86 has voltage - 11. This was in order and working. Apr 20, 2010 · I had the same problem with mine. Good spark at coil and plugs, Good fuel filter. 06-02-2009, 08:57 AM. 21 Sure-Grip Jul 1, 2005 · 87 terminal = the red wire -- should be +12V when the signal conditions listed for terminals 30, 31, and 15 above are met (when the relay "C" is plugged in). Test the relay 20A Motor control, terminal 87 (2) 9: 20A Engine control terminal 87 (3) (petrol vehicles) 25A Engine control, terminal 87 (3) (vehicles with diesel engine) 20A Engine control, terminal 87 (1) (vehicles with code MI6/XM0) 10: 10A Motor control terminal 87 (4) 11: 15A Terminal 15R: 12: 10A Airbag terminal 15R: 13 Jan 22, 2014 · I've checked that terminal 85 has 12v power coming into it. The one at battery voltage will be Terminal 30. One of the most common symptoms of relay problems is inconsistent performance of components such as headlights, turn signals, or fuel pump. Slot 7 is the connection to the coil negative. Locate the relay you wish to test. I also checked the R9 relay, the terminal 87 relay, engine. Mar 23, 2013 · This is the info I've found so far on that relay Terminal 30 - power from Fuse S163 Terminal 31 - ground Terminal 85 - to Engine Control Module Terminal 86 - from ignition switch (D15) Terminal 87 - to fuel pump circuit - Fuses S228, S232, S234, & S243 Terminal C - from crash signal circuit Terminal TK - from door contact switch circuit Nov 18, 2016 · 1. Use an ohmmeter to measure the resistance of the coil, being prepared for three different values. i have everything hooked up right when i turn the key on power gose to GP and I have 12v at both May 15, 2012 · The main relay is a 5 prong relay with 2 terminal 87's. Jun 9, 2024 · When the PCM stops the function of the Asd relay and the fuel pump, terminal #30 will be connected to terminal #87 in an OFF position. Phase protection for small generators that do not use Mar 31, 2017 · Terminals 85 and 86 are the primary circuit used to energize the relay. is present, there is a problem with the WINNEBAGO wire marked "LD" or the accessory power supply. If you are not having problem starting then I would not worry too much. 4 A, the solid ground fault of 2. You should see no resistance A 4 prong relay is commonly used in automotive applications to control electrical devices such as headlights, horns, and fans. If I jumper pin 30 to pin 87, the windows and blower work, so I am sure that the problem is in the To jump a fuel pump relay, you must first locate the relay; it is located in the front seat under the passenger’s carpet. Check from Pin 30 of Relay Base to Battery Negative for +12 VDC. NC (normally closed) - means that the con-tact is closed and current will fl ow between these two terminals. Some items. Depending on the composition of the semiconductor, typical state "1" might be a 5V, 3. Wont run now but ran well when shut down. wo zs iu tz wk rn sf gg sc rx
