Thanks You Guys for the input & thank You Mark for the HeadsUp on the Temp 1 Snsr ID ~ I've had Vanagons in My life for 29Yrs & for most of those Yrs have IDd the Temp Gauge Snsr as Temp! probably due to it being the nextdoor neighbor of the Temp 2 & I’ve never even considered that the IATS had a Temp Snsr # ~ I’ve always thought it strange that the Temp 2 Snsr is IDd as #2 since it seems play the Most Important roll of the 3 as far as Engine Performance is concerned ~ I've long felt that Temp2 should be Temp1, the IATS should be Temp2 & the Gauge Sender/Sensor should be Temp3 ~ So back to Original ? > What in the Temp3 Snsr connection would allow it to send Good (& Norm OpTemp) Data to the Gauge while @ the same time cause the LED to blink ~ I have accidentally created this condition twice on 1 friends Van & have another that is doing similar but have not gotten My hands back on that 1 yet to try to see if the LED will stop blinking by making sure that the connection is optimal ~
