grandteton03079 Posted July 10, 2021 Share Posted July 10, 2021 Hi everyone, first time driving at night last night and when I turned my lights on i noticed nothing in the dash was lighting up, not sure if its related but my engine temperature indicator is also broken… no idea where to begin with troubleshooting this problem. I have an 86 travelmaster savannah and the chilton 1970-88 toyota pickup repair manual handy Quote Link to comment Share on other sites More sharing options...
fred heath Posted July 10, 2021 Share Posted July 10, 2021 Check your fuses. If all are good, it sounds like a ground issue. Your dash lights usually have a ground wire attached to the firewall. May take some searching. Also, check your headlight rheostat. Ensure it’s on full brightness and not dimmed. Temp sender could be a separate issue.

5Toyota Posted July 12, 2021 Share Posted July 12, 2021 if you have those old type glass fuses i would take them all out and replace with new . even if they look good that type can still be bad. somtimes they even fall apart inside but still look fine. make shure to replace with the correct size . i have had this happen too me. took advice from old time toyota mecinec he new what he was about .

Yes being a soft metal they actually stretch with age and vibration reducing their current capacity. So for instance a fuse that should carry 20 amps may be reduced to 15 or less resulting in a false positive. Quote Link to comment Share on other sites More sharing options...
5Toyota Posted July 12, 2021 Share Posted July 12, 2021 thanks for that info i did not think that angle of it but have had the ends come lose . and they will pass a ohms test but fail a real load test . Quote Link to comment Share on other sites More sharing options...
Maineah Posted July 12, 2021 Share Posted July 12, 2021 If you can find the temp sensor on the engine, ground the wire lead to some thing the temp gauge should than read full hot. Quote Link to comment Share on other sites More sharing options...
