Hey Gang, Just bought another 1990 Trooper LS 2.8L V6. I put a new fully charged battery in it and Nothing! No Beeps, Clicks, Dash/Interior lights Nothing. Anyone had a similar experience? Where do I start? Thanks in advance for any help. Lars |

Hey Lars First thing you need to do is check your terminal clamps. Clean them all off and spray them with some lubricant. When I first got my trooper it had a similar issue and I traced it back to a smallish black rectangular box that sits between the battery and the headlights. Now I have a 1991 2.6 so it may be different but if you take the cover off that black box and inside should be a few wire loops covered with colored woven sheaths. These are apparently slow burn fuses. The big black one is the main power fuse which had corroded away on my trooper. A test lamp will let you know if there is power running through the wire or not. I simply replaced that with a new piece of wire and bingo, all was well in the world. So that would be my first recommendation. From there I would try the fuse box. Hope that helps. |

If the fusible links Andrew mentioned above are good, on the passenger-side wheel well is a collection of several relays. The main relay is located there as well, and controls most of the electricity for the vehicle. It's larger than the other relays, and you should be able to test for 12v on the thicker WHITE wires leading to the relay (these come from the fusible links, IIRC). If you can get someone to turn the key while you stand near the relays, listen for a substantial click when the main relay energizes. |

First off I'd like to thank AussieAndrew and kg4miq. The fusible link box was located between the battery and the headlight on the right hand side. I pulled them all and tested them with a multimeter. The last one I checked was the right most link (1.0B) and it had no continuity. It really didn't look smoked, but there was a slight bulge at the terminal end under the heat shrink. I took one off another Trooper (parts donor). When I plugged it in I heard the door locks activate (probably should have DC'd the battery). The Trooper turned over. I primed the TBI and it started then died. Checked the gas gauge and it was empty. Put 5 gallons in and primed it until it would idle on it's own. Shot a little throttle body cleaner in it's throat, replaced a reverse light, replaced the license plate light, got some new wipers and now I have a nice running off road worthy Trooper. Outside of a slight exhaust leak and a stripped oil pan bolt this thing is Bitchin! Note: On the 1990 Troopers there are 4 fusible links in the above mentioned location. From the (anatomically correct) right first is 1.0B (Black), then 0.4G (Green), then 0.3Br (Brown) and finally 0.4G (Green). I have no idea what they link, but I now know the heavy black one links all power functions outside the battery. Thanks again for all your help gang, Lars Edited by 2roopers, Feb 4 2014, 01:28 PM.

Shit you'll never see on the planet. Guys asks a question and gets 2 very informed and spot on responses. Boom, that's what the first gen forum is all about. No Quantunriff-raff allowed here. In the mood to send some poor bastard on a wild goose chase with half-witted, ignorant and inapplicable advice? Keep that shit over at the planet. Thank you fellas, you make me proud. |
