Jupiter Conjunct Ketu, Not Guru Chandal
Jupiter conjunct Ketu is the guru graha sharing a sign with the south node. Detachment colors belief, children, and counsel in that house. Guru Chandal is the other conjunction, Jupiter with Rahu, and it should not be given this chart.

Keep the nodes apart
Rahu enlarges. Ketu cuts and interiorizes. Jupiter with Rahu inflates doctrine, teachers, and sometimes hypocrisy, which is why it picked up the Guru Chandal name. Jupiter with Ketu tends the other way: a belief that wants less, a teacher who leaves, a child-theme that is spiritual or sparse. The house picks the department. In the 9th, dharma itself is Ketu-colored. In the 5th, children and learning are. In the 10th, the career turns away from ordinary status. Rahu will sit opposite, enlarging the far house while this one thins.
Dignity and the host
Jupiter exalted in Cancer with Ketu is a strong guru under a detaching guest. Jupiter debilitated in Capricorn with Ketu is a weak guru with the same guest, a harder belief. Ketu also gives results through the sign lord. If they sit in Libra, Venus hosts them. If they sit in Aries, Mars hosts them. A weak host makes the detachment harder to use. A strong host makes it a skill: research, mantra, a narrow expertise. The 5th house already includes mantra. Ketu there can support practice and still delay the ordinary 5th-house topic of children. Jupiter remains putrakaraka, so children are not abandoned as a subject.
Seven years, then Venus
Ketu mahadasha lasts 7 years and is the sharp chapter for this conjunction. Jupiter's 16 years are the longer chapter, with Ketu's antardasha inside them as the concentrated slice. After Ketu mahadasha the order gives Venus 20 years, often a return of color, marriage, and comfort after a thin Ketu stretch. The conjunction does not guarantee moksha, and it does not deny marriage unless it occupies the 7th and D9 agrees with the strain. Read the house. Refuse the Rahu name. Then read the dasha that is actually on.
Frequently asked questions
Is Jupiter-Ketu called Guru Chandal?
No. Guru Chandal is Jupiter with Rahu. Jupiter with Ketu is a detaching conjunction and needs its own reading.
Which dasha activates it most?
Ketu's 7 years, and Jupiter's 16 years, especially Ketu antardasha inside Jupiter. Venus's 20 years follow Ketu in the order.
Does it deny children?
Jupiter is still putrakaraka. Ketu in the 5th can delay or interiorize that house. The 5th lord and D7, from a sound birth time, finish the question.
